VF900 cu installation question...

[supaidaaman]

Im installing the VF900 cu onto my 7900gt sc co. Should i use the thermal grease that came with, or my tube of arctic silver 5?

AS5

/me readies for JediYoda to explain things...

i used as5 and idle at 40 while cpu idles at 40

 

[supaidaaman]

So everything is installed and its idle is at 36c idle...i think it was about 40 before...

should this be lower?

Load temps are what count.

just ran ATI artifact tetster and after 2min 30 seconds it was still 41c!

wowza! stock was hitting 55+ after that much time

There is no difference using the thermal paste that Zalman ships with there heatsinks and Video card coolers!

I have used both.
No difference at all.
The thermal paste Zalman ships with there coolers is top quality!

Also AS5 is hugely overrated.
Most of the top heatsink manufacturers ship a high quality thermal paste with there products, albiet a very small amount.

But its your call.
I wouldn`t go out and purchase AS5 if I had the Zalman thermalpaste/

Good Luck!

Conclusion!

Load temps with stock evga 7900gt co sc after 3dmark2006 = 65
Load temps with VF900 cu evga 7900gt co sc after 3dmark2006 = 41

but i got 15 less on the 3d mark score 🙁

So does this mean lowering the temp of a card doesnt improve performance? its just in the overclock...

Temps have no impact on performance.

15 3dmarks is well within the margin of error.

I've gotten more than 15 3Dmarks difference with no system changes if I run it multiple times. I found also that *sometimes* after running it a couple times in a row the final score is a bit higher than before because it has loaded stuff into memory 😀

 

[supaidaaman]

so now that my temps are stable 35-41c @ core clock 550mhz, memory frequency 790mhz...

what should i bump the OC up to? suggestions?
