who has a fx 5800 ?

[saaya]

could you remove the ihs of your gpu and tell us what the temp difference is with the ihs off?

berkut removed the ihs on his 5900 and the temps dropped almost 90°C!!!

if the 5800 has the same bad designed ihs it might not need the huge vacuumfx cooler after all...

If I remember reading right, I think he went from 110f to 90f,

90C.... lol. That cant be right. If it was 110C- holy smokes, it dropped to 20... ambient type temps. Hmm.

In my 5800 non ultra (1.35V core ;0 removing the ihs, temps fell down by ~90C (using a Volcano 7+, originally 110-130C (@ 500mhz), after removal max 45C( @ 575), even resitting the ihs properly (its spherical + stock nVidia paste sucks) = +20C to ~60-65C

;)

maybe he means °F, but even then its an incredible temp drop! somebody has to check if all fx cards have the ihs seated so bad or he just had a bad card!

he might be right. My friggin leadtek FX5800 Ulltra runs at 57-60C idle. yep, i said idle in 2dmode. after a single 3dmark run the stock cooling burns my fingers, go figure. btw, Thanks for that pic OPP, now i'm pretty sure i'm gonna get rid of that heatspreader:D

I'm willing to bet its an anomoly. Nvidia knew this product was WAY too hot long before it was released, thats why they went through with the rediculously loud cooling solution.

No way all those engineers working on making it run cooler missed that, it was prolly just a manufacturing problem. Then again, maybe there were alot of manufacturing problems.

look at the temp change! he was aircooling the card with a cpu hsf and got 45°C...

thats the normal temp of the 5800, so the vacuumfx IS not necessary to cool it.

remember ati? they wanted to clock the 9700pro at 350 core so bad, but they didnt manage to do so... and after ther first cards were realeased we all found out why, the shim was too high and the cores had bad contact weith the hsf... even those early 9700s reached 380 with the shim taken off...

[saaya]

bump.... did anybody else remove the ihs?

[ctgilles]

Nope, wasn't my card and Gainward used superglue, because man, my card was bending when I was pulling :D
