xps1330 thermal cooling mod

not good at english

see the picture

 

Very nice...

 

Geez, that would be wonderful if it didn't void the warrenty. Maybe I can swap it out if I ever need service.

 

Damn... you should send the pic to Dell!!!

This solution of yours could save them a small fortune in motherboard replacements...!

Rep this guy, pronto!!!

 

It would be even nicer if members would take the time to at least put what country they're from in the Avatar!

It only takes a few minutes...

 

It never ceases to amaze me how slack manufacturers tend to be!

I expect that if the thermal pad was thinner, it would conduct the heat better but instead of making the headsink mount a closer fit, they fill the gap with a thick thermal pad instead!

That's ignoring the fact that thermal grease is much more efficient then a thermal pad in the first place!

I would do it to my 1530, but the whole warranty thing puts me off

 

I'm more concerned about cooling for the graphic card as it runs at least 10C hotter than the cpu's do... any way to cool that down?

 

Guess what... the nVidia 8400M is the graphics "card" and this is what this thread's all about...

 

I am going to be doing the same for the chipset, and gpu. Where did you find the copper sheets?

I am almost tempted to try with a copper penny =)

 

Make sure its one made in 1982 of before, because those are made of 95% copper, while after 1982 its 97.5% zinc.

 

I hope you are joking...

the surfaces have to be perfectly flat. thermal paste is actually a crap conductor when compared with solid copper, the point is just to increase the transfer of heat between the surfaces, not to conduct heat over a distance.

 

Well. I just got mine back from the Depot yesterday. It's running great. Core temp is around 38 to 40 degrees. I don't have any games to test my laptop out. I did try playing a movie today, and the CPU held steady around 43 degrees Celsius. The BIOS shows A07. Good luck to all.

 

this is a sweet mod. you'll be capable to overclock the system much more with this....definately trying this on the 1530, it would be easy to pull out if need warranty repair. I can't believe how easy it is to get to the processor ad gpu in these laptops. I mean, I have a dv2700t hp laptop and you literally have to take a part the whole thing to get at the processor...(iknow i've done it 10 times)...awesome innovation!

 

Can we get some more instructions than just a picture? As posted earlier, would be nice to from where you got the copper, if you cleaned the surface before attaching the pad and so fourth...

Good job =)

 

This isn't anything new. The idea has been out for a while. I've done it to my Inspiron 8600 (15.4"). Heres the guide for the 8600 maybe you can take some tips from it:

The difference was pretty big on this old clunker, but it was not an easy thing to do. First off you can't just put things back together for warrenty cuz you will be taking off the stock thermal pads and those don't come off all that well.

The biggest thing is getting copper at the right thickness. Very few places sell copper pieces that small (size of a buisness card). If you don't get it at the right thickness ie. too thick then it will press up against the chip when you try to bolt things down.

This causes crashes and lockups like crazy, sometimes it wont even start up. Plus when your gaming the copper starts to heat up and expand, further pressing on the chips. Who knows what kind of damage it could do if the expansion was too quick and too much.

I was out of warrenty and so it didn't bug me much. But I still had to not screw in the cover and the keyboard in completely to prevent pressure crashes. So now my keyboard is a little raised right above the gpu and some of the keys are harder to push/register.

If you are out of warrenty and want to breathe some new life into an old machine by more overclocking then go for it. For a brand new computer, your gains are going to be minimal + warrenty loss = not a good idea. Plus temp isn't always the limiting factor when overclocking.

First off, thanks for sharing your own experiences; I'd definately agree that accuracy is called for here!

But I don't want to OC my M1330, I just want to be able to put in an hour's worth of gaming without it getting damaged. Personally, I don't understand why Dell can't improve their own solution for future-gen M1330s and even M1530s, for that matter... .

 

Since the list of 1330-with-dead GPU-owners is steadily increasing, I thought I'd give this excellent idea a bump...

 

can you use aluminium foil? I cannot afford copper sheets lol

Also can you use AS5 as the thermal grease?

 

So what is the thickness for CPU, GPU and chipset for xps1330?

well the link i posted http://www.greathobbies.com/productinfo/?prod_id=KNS259 that store sells sheets of metal at very small thicknesses. and in small sheets....it's not that hard to find if you look

 

Is there a place to get copper sheets like this in the UK and what thickness/dimensions are required?

 

You guys are silly with your "hobby-store" junk (no offense), just go to onlinemetals.com, give them the exact specs you want and viola! Custom cut and thickness high quality copper sheet in the mail.

 

If I'll keep my 1330 laptop I will definitely try this solution. If something happens on after that, I'll just replace the heatsink with a new one and then send the laptop to Dell.

 

I noticed something wrong (in my opinion) in the thermal modd picture: the spring on the screw should be on top of the heatsink, NOT under it.

This way if the copper sheet will expand due to the heat, the heatsink will have some room to move upwards (max. 0.01 mm I think).

the way the picture shows it there would be no room for the heatsink to move, as it's being held by the screw.

 

if you put the spring on top it will push down on the heatsink too much. Once you open up your notebook youll see its a bad idea. If its even possible

You need to get the correct copper thickness, if its too thick it will expand and possibly crack the die. If its too thin, heat wont be transferred properly

 

It's a long screw, and the spring has to be on top or the system doesn't work. I just think it's a minor mistake in the drawing which shouldn't be looked into too much.

I want to know how thick the copper needs to be as 0.9mm doesn't make contact at all.

 

Let me disagree with you on the position of the spring. If/when the copper sheet will expand it will push the HS up, right? If the spring is under the HS, the screw won't allow it to move up.

If the spring is on top of the HS it will allow the HS to move up. It's logic.

I must agree w/ you on the thickness of the copper sheet.

 

Shame the OP never told us the thickness of the sheet.

 

When you tighten the screw back on with the spring on top, you will realise that the spring will be so compressed that it wont have any travel to go up at all. Yours might be different from mine, since i do have a different notebook but the spring is on the bottom for me

3 thing will usually happen if too much force is being put on the GPU:
-You get a white screen
-Computer wont boot up
-The GPU die will crack

Ive sucessfully done this mod using a 0.65mm sheet of copper. The results were effective. My gpu now maxes out at 72c OC'd. It used to be 80c'ish with the crappy blue thermal pad. Im still yet to complete the 200hour break-in period of the AS5

 

My spring has plenty of travel. No offence but you have a different laptop and that makes the world of difference when discussing this.

 

yeah im aware, though my gpu setup is exactly the same as the picture in the first post

 

Maybe, but it's certainly not the way the m1330 is setup.

 

Flipfire, there's no logic in arranging the screw and spring the way you're saying. It wouldn't make sense.

My GPU, as I said, has 80-82 degrees Celsius when gaming Simcity. I believe that doing this thermal modd it will drop temps like hell. It's a good thing to do and I'm even willing to use Arctic Silver Adhesive I have right now, for glueing the copper sheet to the HS. I don't care about the HS. If I get into trouble I'll just find a new HS.

 

Could you replace this to stock if you had to for warranty?

 

interesting

 

I can always get a new HS from eBay and swap the modde one with the new one if I have to go to warranty, although I strongly believe that the mobo issues are related to the heat the video card produces. Heat that after a period, 6-7 months, kills the mobo or the GPU.

 

Very interesting. This, plus a laptop cooler = 800/1100 ? :-D

 

Hehe! No, I don't plan on OCing. I just want to make sure my mobo doesn't get fried up.

Is it bad that I look for the best for my laptop?!

 

I can confirm that it is easy to replace the soft blue thermal pads if need be.

 

Awesome, I will be ordering the copper then.

 

0.9mm or less is the wrong size.

 

Did you try this thermal modd?

 

No, my fan died so I had a fiddle with the heatsink.

 

Which company sells the same exact pads (a link would be grand, thx).

 

You peel them off and reapply.

 

Lol, well that makes things easier...

 

For the record, I partially tore mine peeling it off. Your safer with a razorblade (used to "lift" the pad off the HSF, not to cut it off...).

Thx to Lao for the tip

 

Hi folks

Really interested in this copper plate mod for my 1330 gpu as the temps go over 100 on load!

Just reading through this some have said that 0.9 doesn´t make contact but others have great results with 0.65.

Does anyone have a set of dimensions to use?

 

1.5mm seems to be the correct size for the m1330. See this thread for the guide
