IC Graphite Thermal Pad Available for Test and Review

oh dear....time to spend more money.......

any of you guys want to test first rather than a disabled guy on SSI and a fixed income? can't afford to be the tester.

 

Did you miss the whole discussion or something. Because IC Graphite Pads ARE rebranded/labeled/repackaged Panasonic Graphite pads.

 

At this point I would suggest that nobody else spend (or potentially waste) money on it yet, or speculate whether it will be good or bad.

We will soon remove any doubt, as I will have the 700w/mK stuff on Monday and we will see whether it is good or garbage for laptop cooling.

 

Just found the Z-axis information: it is 15W/mK for the EYG-S style sheets. This does not mean it is bad, but rather it is halved what the "Z optimized" variant does on performance. This suggests that lapping or well machined parts for heatsink and IHS will perform better for this type of variant.
http://docs-europe.electrocomponents.com/webdocs/1181/0900766b811810f2.pdf

 

Looking forward to see your tests!

 

Also, that document I just posted shows that, if possible, cut the sheet closer to the size of the heatsink, not the IHS. The larger the sheet, because it spreads the heat more evenly to the edges instead of just the single hot spot of the heat transferred to the IHS, will allow the sinks copper to have more transfer surface and may compensate for the lower Z transfer rate. This is easier on laptops than on desktops as gravity can keep the contact with the sink instead of it hanging over, potentially touching electrical components. Use your best judgement on size to use, but something to think about.

 

Missed that with the soft PGS. The "Z" optimized sheet says 13W/mK. So Soft PGS with the ZL in the sku seems to be what IC is using, potentially. But, ZL is not the type that the rest of us were looking at and is not indicative of the EYGS without the ZL.

 

Can you spare an old guy some agony and link me to the high W/MK versions of the actual Soft PGS variants?
Please?

Well, dammit. Wish I had not wasted money on it now. $24 flushed down the toilet, just as I had feared. Too late to cancel it, so I will go ahead and test it to confirm that is it a waste of time. Phobya NanoGrease Extreme is 16W/mK so, a 15W/mK solution for me is utterly pointless versus using liquid metal. And, for a laptop, even more so. I won't even consider wasting my time applying this on my desktop. Those specs should be clearly posted on the product information page. Only stating the X/Y rating of 700W/mK without the pathetic Z rating of 15W/mK is misleading and deceptive.

 

Nothing is wasted, it all serves to cement our understanding of what is out there. I have a feeling liquid metal compounds will continue to reign supreme

 

In concept yes... but, it's my $24 getting flushed down the toilet, LOL.

I think you're right on the liquid metal. I never really expected anything to beat it, but thought maybe this could take the middle ground between paste and liquid metal. And, that still might be true in spite of my skepticism.

 

I hear ya, but needed to dig deeper to find it. Now, we have seen lower W/mK actually perform better than higher rated, but it varies on use, pressure, etc. Look at how low IC Diamond's W/mK is and how it beats some pastes with higher W/mK, as an example.

 

Yes, that is true. IC Diamond is a good example of how it is true.

Perhaps a piece of soft foam like I use for liquid metal dams placed between the CPU and heat sink, (around the perimeter of the CPU, not on top of it,) on the CPU side of the graphite sheet, could hold pressure against the heat sink cold plate to help transfer the heat. If the graphite sheet is not pressed against the heat sink, I don't see how the X/Y thermal conductivity will be meaningful. The overhanging graphite pad itself won't do anything if there is no place for it to transfer the heat. The pad would have to be gigantic to function well as a heat sink in and of itself.

 

That is a great idea, which also adds some mechanical force. Without pressure, it would have limited effects, but still could hold the heat there, just with less transfer rate. What I meant with that part is that we think of the sink in relation to how we have it positioned for assembly, but flip it over otherwise. But without the mechanical force, as you suggest, the transfer of heat is severely lessened. Great idea to try out in this project.

 

I looked at that PDF, and it DOES look like the Soft PGS is the 28 W/MK version, but it seems from what I'm reading, that the BASE W/MK is 28, but the higher numbers are on the X/Y plane, not the Z plane.
The other sheet you mentioned is STILL 13 W/MK. I read the PDF clearly. The T series that you linked is 13 W/MK.
That's the stuff that IC cooling sells.

 

THIS.

Lots of factors involved here. And mainly these tests are not controlled.
Desktop performance will always be better than Laptop performance.

And how well a paste fill in gaps and maintains its viscosity under high temperatures.

 

Update: Dud laptop must be sent back asap, new laptop is here, PGS pad also here. Wife at graduation ceremony with family, going to eat dinner with them and begin testing later tonight will post results on the dud 13r3 and will work on the other unit (15r3) once my traditional thermal pads arrive on Monday and after I inspect the unit itself. Not going to repaste the GPU because frankly I don't care so we'll focus on the CPU first.

Baseline:
Package - 93*
Cores: 91*, 86*, 93*, 79*

 

Classic BGA Alienware core differentials lol

 

it's a feature, not a defect

 

Sitrep: It works, and it works well. I took no care at all with the install as far as leveling, screw order, nothing and here are my temps. Keep in mind this is a ****ty 13r3 as stated earlier. Previously it was on a cooling pad, this is from me laying it flat on a cloth couch.

EYS-S Pad Baseline:
Package - 77c*
Cores: 76*, 74*, 73*, 72*

Update#1:
Watching my core temps at idle is spooky - 48/47,47,46,47. Everything is pretty much within 2C* of each other, so I'd say this is an overwhelming success. Also keep in mind fans are off and its 80F* cuz the AC died today lol.

I think we have a winner! This is almost on par with my LM temps also this was taken at 80F*

 

Do you have normal thermal paste or other units to test the eys pads on?

 

Once I get my Fujis I'm going to move onto a fully padded setup using a 15r3 on Monday/Tues but I will tell you that fully loaded I was seeing around the same temps using conductonaut which to me is very impressive. The fact that this is a permanent pad that wont erode the heatsink is pretty shocking to me.

I was fully expecting this to be a dud with the low pressure but no this is within 5C* of LM I've used.

 

For those who don't understand what I mean by spooky I'm talking about this. Granted the current temp doesn't match because of load varience but as I watch my machine the core temps are all mirroring each other in ways I've never seen before, ie all cores and package all read 55C* at the same time. For example look at the idle temp. I've never seen that before, not even with Conductonaut so the Z-axis cooling is definitely the real deal.

 

Which pads do you have? the 28 w/mk pads?
I only tested on a r9 290x, and my results were abysmal, probably because the mounting pressure is simply nonexistant. I mean, when LM just hardens up and gets ALL Absorbed because there is literally no pressure at all on a reference sapphire (old original reference) 290X, with wimpy tiny springs and that X bracket....

And with the metal bar in my spine, i can't test the 2600K desktop CPU, and I'm not removing LM from my laptop with this pain either......

 

I bought the .2mm pads. Part number: EYG-S0309ZLAK; also on a side note this is plenty material. The nubs on the side of the strip are by themselves enough to cover the CPU. I'd say I have a good 10-20 CPU application's worth from this single strip

 

The 20 W/MK one? That's what it shows when I search for that part number.

 

Still trying to test and boot the 15" what I provided is the part number listed on the package from Pano so whatever it says it is. Very happy with it to be honest, works as advertised and it really isn't a pad as much as it is a thick sheet of foil. Definitely seems to be working because with minimal effort I've shed almost 20C* across the board so I definitely intend to do a complete repad of the 15" once the Fuji's arrive on Monday

 

Interesting footnote, there appears to be a break in period for PGS. As I'm browsing around the temps have further stabilized. Take a look, if this isn't the cleanest spread on a BGA Alienware it's damn close especially since this is with a already aknowledged defective unit/heatsink

 

I bought this one.

https://www.digikey.com/product-det...c-components/EYG-S0909ZLX2/P122034-ND/6575964

Seems to be the same type as yours but different size
but it's horrible on a sapphire r9 290x reference card!

 

If you're thinking I did anything special all I did was cut a sheet to be roughly the same size as the CPU die, screw the screws down in a completely random order all the way to the end of the thread and booted because #1 IDGAF and #2 I wanted absolute worst case so I could justify shelling out for the Fujis and the effort to disassemble a new system I'm unfamiliar with.

All I can say is that I am happy with what I got result wise and intend on doing the same on the 15r3 once I get it booted, updated and the parts arrive.

 

Works probably due it's thikness on AW's "nice" Tripod HS. With use of thermal paste (who is thinner) will this probably means worse contact between die/HS. Aka you will get worse temp.

 

Mine came earlier than expected. Got it today.

And, it was a waste of money. Abject failure, LOL. Back to liquid metal and regular thermal paste. Wish I could get my money back from Digikey.

Before I throw it away, I will test the piece I cut on my desktop CPU and see if it fails as hard as it does on the P870DM-G.

Edit: Put it back together with Phobya NanoGrease Extreme. Added third screen shot to compare with XSPC K3.

 

How the HELL is @Sentential getting "Almost LM" temps on his then?
I don't understand?

I really don't.

Thank you for the test, brother @Mr. Fox

 

I don't know. Maybe he got lucky with perfect contact or something. What clock speed is his CPU running? Did he run something like wPrime 1024M or Cinebench? My temps seemed pretty good until I subjected it to a brutal CPU test and then it turned to crap.

Proof will be when I try it on my desktop with flawless contact and extreme pressure. If it is not as good or better than thermal paste there, then it's a waste of time and not worth messing with. I'll be back with those results in a little while.

 

Well, forget that. Desktop temps are absolutely HORRIBLE. Hit 90°C in wPrime 1024M in like 5 seconds at 5.4GHz and I normally see a max of around 78°C after the full test. If anyone wants this piece of crap and willing to pay the shipping let me know. Otherwise, I'm throwing this worthless feces in the trash. I'm done with this graphite pad bullcrap, LOL. Total waste of time.

 

So, I know he was using soft PGS and you used regular PGS with lower Z transfer. @bloodhawk used the "z optimized" EYGT. Did anyone here aside from that test with EYGS with ZL in the sku indicating it is soft PGS?

 

The results would look prettier with stock clocks Probably a reason the BGA model had better results. And all I have seen until now is as expected

 

So let's get this straight before everyone wastes their money here??????????????????????

https://www.digikey.com/product-det...ronic-components/EYG-S091210/P12726-ND/678309 <------this is REGULAR PGS?



https://www.digikey.com/product-det...c-components/EYG-S0909ZLX2/P122034-ND/6575964 <---this is SOFT PGS????????????


So Mr Fox ordered the wrong one and it's my fault

Sigh, jesus people.
I really dislike it when people just post pdfs and things expecting everyone to understand everything before money is spent.

Can we make this CLEAR instead of just people saying OMG THIS WORK THIS WORKS IDGAF??


https://www.digikey.com/product-det...c-components/EYG-S0909ZLX2/P122034-ND/6575964 <----this is the right one to order? SOFT PGS?

or is there a DIFFERENT ONE?

*I* ordered this one: https://www.digikey.com/product-det...c-components/EYG-S0909ZLX2/P122034-ND/6575964

PART NUMBER: EYG-S0909ZLX2
was this the CORRECT PART ??????????????????????

But on my r9 290x, I see slightly worse temps than Coolermaster Gel Maker Nano, about 4C higher. Thus I'm not using it.
And I have a metal bar in my spine with extreme swelling so I can't test my desktop right now. I can barely walk. I barely can use my right leg because of nerve damage because of the scoliosis (i have marfan syndrome).

Sorry for being handicapped but its not my damn fault. I *INJURE* myself just trying to re-LM my own damn laptop !!!!!!!!!!!!!!!!!!! while all of you guys just 'OH LOOK HOW EASY IT IS !!'

please dONT FREAKING POST PDFS. Post LINKS. DIRECT LINKS. Don't confuse people. Some of us may not catch on as quickly as others.

 

This is the one i ordered. Please read my ABOVE REPLY please.

EYG-S0909ZLX2

That's what i ordered.

https://www.digikey.com/product-det...c-components/EYG-S0909ZLX2/P122034-ND/6575964

 

Yes, that is the soft PGS which has better results. That is the one that @Sentential used. Now, if that is the same as what is in the IC packages, which at this point we may assume such, then the other tests performed by @Mr. Fox , @Raidriar , @Mobius 1 , etc. come into play.

I was reviewing some of the earlier posts in this thread for comparison. It seems that these pads are useful, especially if doing no or light OCing. Once you head into heavy workloads and heavy clocks, it gives way to high quality pastes and LM.

 

The IC pads are the 13 W/MK regular pads, not the soft PGS. Someone posted this several pages back. But now I made @Mr. Fox waste his money because i failed to notice that what I linked was not soft PGS(I THOUGHT IT WAS) and its all my goddamn fault. I'm sorry.

 

Then those are "Z optimized" EYGT sheets. That means what you got may perform better than the prior use. I look forward to the confirmation. It is a shame, but I also linked that specific sku, so do not beat yourself up for it. Right now I'm suffering from chronic headaches. Had I waited to chime in until I dug through all of the research, then it may have come out differently as well. Either way, the truth of the matter is that we now have one more data point, even though it is a shame to waste money. Granted, the only test not performed is the comparison of thickness in the standard PGS line, but at this moment, it seems that it may not be worth the testing. So, keep us appraised when it comes in and of your results.

 

Hey, don't worry about it, bro. Life goes on. Simple mistake. I didn't need it, but it was my decision to order what you suggested. At least it was just a day or two worth of lunch money. No harn, no foul. Plus, I think I have pretty much confirmed this stuff ain't going to work for systems that are heavily overclocked. It's just not good enough to handle that.

I look forward to seeing your results with the soft stuff. I am very skeptical, but I have been wrong more than once. If it were me and I knew what I know now, I think I would cancel the order if it hasn't shipped yet. But, then we would never know if the soft stuff is OK for overclocked systems unless someone else tried it.

 

I have the soft stuff right now. But I can't put it on my 2600k because of my back problems right now. And I'm not going to redo the LM job and injure myself trying to disassemble my laptop. my god, being 6 foot 6 and having scoliosis and a metal bar in your spine....i mean.....its like...why am i even alive? why? why do i have to just sit here and suffer?

 

so @Falkentyne
You want me to buy this one and test?

https://www.digikey.com/product-det...c-components/EYG-S0909ZLX2/P122034-ND/6575964

Or is the soft pgs a different product number?

 

Yes that is soft PGS.
If you dont mind buying one, yes go ahead.
I just can't undo my LM job on my laptop. I have to bend over too much to unscrew, clean and scrub stuff.

 

And this is the one that give best results?


IIRC there's one you posted that was 700 and 1000w/mk, did anyone ever try that?

 

Even I was impressed by that result.

I think @Sentential lives with Galactus in deep space and gods helped him achieve LM like results.

I'm seeing for the first time on Mr fox desktop hitting 90C.
