Applying thermal pads on SSD and RAM

i am a cooling enthusiastic and i want to feel my notebook as cool as possible, so i bought 2 mm thermal pad to put it above my 2 SSD and RAM. AW15 R1

 

Showing only your after temps means nothing without any before temps.

I'm cooler with no pads.

 

correct, but your SSD is 2.5" mine is m.2 SSD a lot of difference in heat
the temperature before was like 48-50°C, i live in Ibague-Colombia and here the weather is hot

edit: i want to add that i dont use cooler pad.

 

Ah you decided to pad it up. Those are some super thick pads. I wonder if it helps for the ram.

 

DOesnt it become like a thermal shield instead? I thought pads only work similar as thermal paste and need an endpoint to put that heat away?

 

i was thinking the same, but only if the pads had somekinda chemical which can cool things.. may be in future lol.. concept of passive cooling..

 

you can think it in this way, but when i am gaming, the 2 fans create a vacuum flow of air and my temperatures go down quiclky

 

i am a mechanical engineer, i know things about thermodynamic, heat transfer, metals, polymers, ceramics and properties.

 

where did u get that thermal pads from..

 

Oh thats nice, didnt expect that too be honest. So for you it makes a difference? Looks like some heavy duty thermal pads by the way.

 

EBAY.COM just make sure the thickness is 2mm. I am happy with this thermal pad (3.2W/mk) is a low conductivity, but the pads are very sticky ecxactly that i need it. the 6W/mk pads are expensive, and more than 6W/mk are weak and tend to break. forgive me for my engish, i speak snpanish.

 

thanks, no problemoo.. even i dont speak proper US english or british accent.. so ur welcome

 

My CPUID HWMonitor doesn't show my m.2 Samsung 950 Pro ...hmmm... however, my Samsung 850 Pro SSD shows a temp of 26C without pads....I'm curious how much I can improve the temp....

OP, did you have to do anything special for your CPUID to show up?

 

your samsung 850 PRO is a 2.5" drive, mine is m.2 SSD, your m.2 950 pro surely run hoter than 26°C. If you open your samsung 850 pro, you will find thermal pads on the memory chips and the metal plate function like a thermal passive dissipation. The m.2 SSD or m.sata ssd dont have a case

 

Correct. I was referring to the 2.5" drives temp, not the m.2.

I'm going to put some pads on the bottom of the m.2 and have it make contact with the copper plate that's under it to dissipate the heat.

Er
Thermal pads on ram, but there's no sink to dissipate the heat?

 

You may think you know everything about metals, polymers etc but you know nothing about cheap 2mm thermal pads. Honestly I believe that 2mm of such thing is more a thermal shield than a thermal transfer.

And don't trust that marketing numbers, you can't test it so most likely they tells you nothing.

 

if you want to buy 11W/mk Thermal pads(and your wallet can afor it) you can do it. I am just fine with the 3.2W/mk and i proved it, my temperatures go down
i made a re-paste with thermal grizzly conductonaut too

 

No tape to protect from potential shorting out?!?!

Also, I never really noticed when I re-pasted mine but looking at your pictures, the GPU and CPU seem to glued at each corner into what I can only assume is a socket...... I thought BGA was soldered?!

 

if you look closely, i applied a high temperature resistant resin

 

I honestly wonder how much of that reductiuon is due to the liquid metal paste? I got good results when I switched to Coollaboratory Liquid Pro/Ultra. I've having a hard time seeing how a thermal pad does anything to dissipitate heat if it's not in contact with another suface to exchange that heat. I'm not an electrical engineer but it just doesn't really make sense.

 

Smart. For Gpu especially.

Back to thermal pads. I wrote that based on many negative feedbacks from people about 1$ 1mm Chinese pads and you have twice thicker.
Heck, I bought 0.5mm one and still think if that will transfer any heat while you bought 2mm one.
Afterall I didn't see how temperature changed, only what is now and I also don't see the RAM chips temperature where I am 100% sure you done worse. Just IMO, you may think otherwise.

 

the difference between liquid ultra and TG conductonaut is 1°C ... TG is better 1 grade

 

Couldn't see that to be honest, but glad to hear you've used something.

I will no doubt have to change the Kryonaut I currently have in my machine so I intend on using the CLLP I have left from my desktop build.

What is the resin you have used?

 

Hello, after seeing your post, I bought 145x145x1 mm arctic thermal pad with 6.0 W/mK. I am not an expert in all this. Can I just go ahead and place it on ram, ssd like you shown or do I need to take any safety measures? How should it be done to be effective? I have an alienware 17 R3 with 950 pro.

 

yeah .. is easy .. i think that 2 layers of that pads should be fine .. like a sandwich .. 2 mm is fine

 

and wash your hands .. i think is a little bit toxic

 

I have 1mm pad with 6.0 W/mK. Is this fine or should I return it and get 2mm one?

 

Also I see here they use copper shims first and then place pad on it. Is that how it should be done for effective results?

 

you dont have to return it ... that is why i said you ... 1mm +1mm = 2mm tick .. so you only have to put one above the another that is all .. and you can add shims of copper above if you want but i think that you can make the layer of thermal pad enough tick to make contact with the back lid .. that is what i did .. i have 2 of 2mm so .. is 4mm tickness layer .. so you should try layer by layer .. i had artic on vrams and a cheap thermal pad on SSD´s and did the work fine, now i have fujipoly of 6W/mk on SSD's too, and the temperatures are better. the back lid will act like a big passive cooling, that i think is better than copper. i used both and i found that is better the direct contact with the back lid. they have better results with copper because is a desktop and it manage air flow inside the case, and this is not the case of laptops. i hope i solved your question

 

I am not sure if it would really act as an heatsink. As far as I know it is only made for heat transfer. This is like putting thermal paste on everything. But it needs something to move that heat to. But that is my theory.

Some real tests should be done with this.

 

Okay hmm.. so it should be in contact with the back panel.. TIL.. I doubt pads on your ram are in contact with the back panel? Also I see a pad on top left. What is in contact with? The body of the laptop?

Like these tests?

There they are spreading the heat through the chassis. Just thermals pads on top of a heat source is a different matter though i think.

 

Here the OP is spreading heat through the back panel. Pads are in contact with the panel.

 

The backpanel is plastic, it would act as an insulator. Especially when there is the lack of airflow. In the end, stock with a good repaste these machines run sufficiently cool to begin with without any hacks.

Sticking thermal pads on every parts in the machines is not helping cooling a lot I think.

 

in fact is not plastic, is a composite about polycarbonate + carbon fiber so it act like a passive heat spreader

 

yes, my ram pads are in contact with the panel too in your model with DDR4 is not necessary, but lowering temps is always better, because you will gain more room for overclocking that is exactly what i do. the up left pad you see is above the PCH that is a pain in the ass on my model ... you can add 1 for improving temperatures dont have to be in contact with the panel

 

Its an insulator not a heat conductor. I kno the material, but the properties are similar to plastics. Polycarbonate is plastic Carbon fiber is not a conductor as well.

 

when you test it as i told them you can suggest is an insulator ... and i think i know better about materials than you, i am a mechanical engineer

 

@rinneh the thermal conductivity of carbon fiber is between (21 and 180) W/mk, better than the thermal compound you are using, and i am talking about the worst escenario, 21W/mk
on the composites the materials acts a lot different, and i am bored trying to explain technical things on english, my native language is spanish

 

Do any of you guys know where to buy Thermal Pads that are from within the UK that reform shape and are of 7kw+ without the cost please?

 

Arctic or Alphacool 6/7 W/mk are soft thermal pads.

 

Thanks for the update. Just recorded temps from my nvme pcie drive of 107%.. The original post is a good call.

Thanks

 

my temps with 2mm heat pads.did the same thing. I think it helps! London weather!

 

If its under full load,then these temps are good.

 

is not under full load! these are temps on general work.anything I do on my laptop but not gaming.games does create more heat but nothing too bad.
