Alternatives for adhesive thermal paste (epoxy like grease) for sticking tiny heatsinks to VRAM, VRM, and other stuff on GPU PCB?

post #1 of 12

Hey all!

I have an EVGA 980 Ti FTW ACX 2.0 and an Artic Accelero Xtreme III. I found out I can't install it properly without removing the front plate. So I'll have to remove the front plate meaning I'll have to stick those silver little heatsinks on the PCB. Like on this picture below.

Thing is the thermal compound provided by Artic is epoxy like and will permanently bond the heatsink to the PCB components. I don't want that. I'd like to be able to remove them easily (or at least without difficulty) in the future if I have to. So does anyone know of good alternatives to this? I can't use normal thermal paste as it'll slip off when the components get hot, I need something that is sticky enough to stick them together.

I've seen these alternatives:
Ceramic thermal paste
Thermal pads
Thermal tape

I have no experience with any of them so I don't know if they can do what I want to do with them. So yea, anyone got any experience on these? Or other alternatives I missed? Also if you got any recommendations for a specific product, I'd like to hear that as well!

Thank you!

Sekisui thermal tape works really well for this application.

It's available in sheets and on a roll in different widths and sizes and is fairly cheap on ebay.

Sheet

Roll

Above links are examples of ebay adds.

I use the roll for GPU VRAM and VRM heatsinks and it sticks very well and conducts pretty good.

Only downside is that the components have to be degreased (isopropyl alcohol) and cleaned very very well and VRAM usually only sticks properly if you use the pencil eraser trick on it first to clean it.

It's easy enough to remove i as well. Just puling it won't do anything but if you twist the heatsink around it will break the bond of the tape and it will come off pretty easily.

I'm using it on my ghetto 980 cooling mod as well. Accelero IV backplate, Accelero III heatsinks on the front, with a Gelid Icy Vision Rev 2 as a cooler tongue.gif The accelero won't fit in length with my front mounted CPU rad tongue.gif

So I did a bit more research about this, learnt a new measurement, "# w/mK" supposedly measures how well a material conducts heat. That Sekisui 5760 apparantly has 1.3 w/mK. I looked and it seems like thermal pads are much higher for some reason? At highest there are 17 w/mK which seems insane as something like Arctic Silver 5 has 8.7 w/mK lol.

I looked around and it seems like at europe I can only get the Alphacool Eisschicht thermal pad 14 w/mK at a reasonable price. Would you happen to know if 1mm and 0.5mm have any difference if all I'm doing is sticking a heatsink on stuff? I understand normally you have two sides squished together, and the thickness has to accommodate that gap specifically. But since that doesn't apply here, will it matter if I get 0.5 or 1mm?

Those Alphacool pads look interesting until i saw the price.. The reason I use Sekisui is because it's dirt cheap smile.gif. And always take numbers they throw at you with a grain of salt ofcourse..
17w/mK is half of the conductivity that like, Coollaboratory Liquid Ultra has.. It's not very believable.. Neither is the 14 w/mK from Alphacool..

I'm in Europe as well and if you pay with paypal most ebay vendors just ship worldwide. Wasn't very expensive either for standard mail shipping. Took about 2 weeks for them to get here.

From the few reviews I saw, it seems the alphacool pads does perform better than other pads with lower w/mk values.

Too bad 980 Ti do not have VRM temperature monitoring... Or else I could do some tests myself on the pads.

From the few days of research I done, I don't think anyone have ever used thermal tape on VRM. Only on VRAM. Meanwhile some people have used thermal pads on VRAM. So may as well go with the pads. Thanks for the suggestion though!

Anyways, I went ahead and bought the alphacool eisschicht 14w/mk 0.5mm pads. Not cheap but wasn't absurdly expensive either. 25.84 euro/20.31 british pound including shipping for two peace of 120x20mm. The 100x100mm piece had a much better value but bleh, I don't want to spend more than I have to... Let's hope this goes well. If it does, I might put up a guide on how to install the accelero xtreme iii on a 980 ti ftw as well as brief reviews for the pads. Certainly haven't found any guide for installing this cooler on the 980 Ti, nor found anyone using thermal pads to stick free heatsinks on vrm/vram...

Hwinfo may be able to monitor the vrm temps if there's a sensor for them. Use that program and see if you can find it. I've got a vrm temp sensor on my 970 strix. I used ceramic paste and epoxy mix as a thermal glue and it worked quite well. Over time the glue became more brittle so a year or 2 after I installed the heatsinks I was able to just twist the heatsinks off and apply the stock cooler again. I've read it's a big no-no as you can break the actual chips off but I didn't need much force to get them off so it was OK.

Super Glue works very well. Only problem is it takes acetone to dissolve / loosen it, and acetone eats many things made of plastic. In other words, it kinda permanent.

Used HWinfo, nothin.

Not suprised, many 980 Ti I've read online did not have VRM temperature... Guess I'll have to save up for a infrared gun. As to that ceramic epoxy mix, do you still remember what formula you used? 50/50? 40/60? etc?

Lol well, that's a big nono for me then xD. Still, thanks for the suggestion!

@crystal6tak, I used a 50/50 mix of paste and it worked just fine. I'd be very cautious about using it tho as it may become permanent..
