most effective r9700pro air cooling

[Xevuhtess7]

whats the best heatsink/fan? i want to take my overclocking as high as possible. ive read somewhere (i forget where) that getting a 1u slimline cpu cooler is very effective. is this true?

[Ugmore Baggage]

AFAIK, the ridiculous looking Zalman is the best.

What ever happened to elegantly simple copper sheets? I love the way that each copper fin contacts the CPU before passing through the vise and then fanning out... art meets science (ahh blabbering, how nice, better go to sleep... plans to dream of heatpipes leading to multiple 6000Cus)

heatpipe or 1u cooler?

[EclipseJP]

I think that was a heatpipe answer.

[Xevuhtess7]

its kinda big and clunky though.... doesn't have a fan on it either. sorta expensive too, im looking to not pay ver much. cooljag or thermaltake p4 1u cooler anyone?

[Evnas]

Cooljag and Thermalake are both very good companies, so i think u would be good with either. But the Zalman Heatpipe is really a damn nice cooler, and its amazing how it uses no fan but can get cooler then most other coolers out there.

My cooljag 1u does the trick, but I've never heard about these passive cooled heatpipe things?

i think ive decided to go with either a thermaltake p4 1u cooler or the coojag (depending which i decide looks better :)). but how do i go about mountin this onto the gpu? im planning this for a r9700pro by the way.

[Xevuhtess7]

someone help? how do i mount it.....

[OC Noob]

Mount it with Arctic Alumina adhesive.

I would recommend removing the shim too as it is very easy and you're going to have the HSF off anyway.

[Xevuhtess7]

does removing the shim help cool better?

Yea...otherwise the HSF wont come in direct contact with the core

[Xevuhtess7]

do you have a link with instructions on how to do this? i dont wanna end up messin up my card. also, i think ill get 2 of those 1u coolers, 1 for the core, 1 to cut up and make into ramsinks. is it a good idea to put another heatsink on the opposite side of the core and mem?

[OC Noob]

I should save this to word so I can cut and paste it:


Stick the 9700 in an anti-static bag, then stick it in the freezer for 15-30 minutes.

Next, slide a credit card or thin platic card between the shim and the HSF. Stick a flat head screw driver between the credit card and the HSF the pry it off.

It will take a bit of effort, but the HSF should pop off and land somewhere in the next county. The cridit card should protect the core/gpu from gauging/scatches if you are carefull.

Next, clean the adhesive off with nail polish remover, doing a final cleaning with Isopropyl Alcohol (what your girl friend typically uses to remove make up). I wonder how well makeup transfers heat?

Anyway, then you can use a razor or thin knife to stick between the shim and the green (PCB?) that the core is mounted on. Pry it off. It doesn't require freezing as the adhesive used on it is much weaker then the thermal adhesive used on the core/HSF.

Ardctic Alumina is the best non-conductive thermal adhesive, but is permenant. Some people preffer Arctic Silver adhesive, but it is slightly conductive and if you are not careful you can fry your card.

To remove something stuck on with Arctic Alumina you can blow hot air on it with a blow dryer to heat up the HS. The HS will get VERY hot the remove it using a twisting motion so you don't crush any caps. It takes a bit of effort, but will come off.

Also, be careful with the heat as the boards are sensitive to heat. I'm not sure what their threshold is, but be careful.

[Xevuhtess7]

why do i need to freeze it.. shouldn't i warm it up so the adhesive is warm?......

[pip]

the adhesive becomes brittle and breaks more easily

AMD retail heatsink seems to be doing pretty well on my 9700pro's VPU, even with the shim still in place.
