High Quality Thermal pads for 280 WB?

[BobbyBubblehead]

Maybe my shader doesnt want to go beyond 1458
But my other theory is the thermal pad isnt a very good one.

Where can I obtain some high quality pad that conducts heat better?

If I can get hold of some I may just try a re-mount :)

Anyone point me in the right direction to order some (poxy UK shopper #Laughs#) its bleek round here for thermal pads, need a slow boat order.

I am quite interested in the result. Wouldn't it be better to use thermal paste for the core ?
Actually I thought pad is only used for parts with low heat output like rams etc.

Well I just followed the destructions as supplied by the WB manufacturer... maybe there has to be clerance to allow for expansion. The original pads were not re-usable after the First GTX280`s power choke blew.

Theres about 1mm clearance on how the blocks milled so no doubt some pad has to be present on the shader.

I did use thermal grease to help keep the pads in place when assembling and to improve the conductivety between chip, pad & block.

Someone on the forum said before they have different ratings if you can source thermal pads.

temps are low anyway so it may be to no avail... but im curious to find out if I can get to the next stepping but even with 5`C generally back from a new board it still throws floating point errors at the next stepping.

Hope I can find some worth swapping out with.

I've used these pads on ramskins before, and they seem to do a pretty good job: Akasa Thermal Adhesive Tape AK-TT12-80 (http://www.sidewindercomputers.com/akthadtaak80.html)

What do you mean by shaders ? The shaders are in the gpu.
The block is milled bit deeper for non gpu components because it would be a nightmare to cater for every manufacturer's card but they tend to use the same gpu so the block should fit at least on that part without pad.

I meant the chipset chip sorry, its my shader clock thats slightly dissapointing me.
I ended up using pads maybe a little too thick and there was clearance on the chipset chip, also messed with the screws to fit the back plate (different manufacturer to the WB)
theres probably a bit of tension in the card with the current pads because the original print from the thermal paste wasnt very good first fitting on the second card.
was much better with the original pads but it was a defective card and the power choke blew.

Currently its running at core712 shader1458 mem2646 so its worked fine for a standard speed GTX280 but I carnt help but feel its kind of clamped un-willingly between water block and ram sink, the chipset chip would have made contact fully otherwise.

only the third water block i`d ever fitted at that point... just needed pads maybe with half a millimeter less thickness.

just that fraction too thick once id carefully took the screws down.

if only the first card wasnt duff all would have fitted well #Chuckles#

I think with my card theres a slight build up of heat round the chipset chip that just sets off the floating point error but thinner pads and better pressure on the GPU could make a difference.
seems that end of the card suffers with the current from the Motherboard as well.

not really sure how I managed to get the clearance, maybe i put a pad there to even it out when I took the screws down... whatever I did I took my time and had to improvise a fair bit, it just got akward.

would like to redo it right with the correct thickness and thermal conductive pads see if it improves anyhow.

Chipset chip? Are you talking about the northbridge???

[BobbyBubblehead]

xspc refer to it as the `chipset chip` on there modding diagram through process of elimination GPU, RAM & Chipset (to be coverd with thermal paste)
its situated near where the third power source that feeds into the card round where the power choke is situated. (other two feeds being from the PSU)
whatever chip it is, Ive stuck a heat pad under it like a Dingbat, but as I`ve said the pads were slightly the wrong thickness for the job and caused the block to not seat quite right.

dont think the 280`s supposed to be stable below the speeds ive got anyhow but I would have another go at doing it right... third time lucky :)
