nVidia IHS removal = -6*C

[ThugsRook]

i removed my BFG5900's heatspreader.
it was very easy.
i see a 6*C drop in max GPU temp while looping X-Isle tech demo in a 1152x864 window for 30 mins.

BFG5900 @ 510x950
with IHS = 80*C
w/o IHS = 74*C

:cool:

not my pic, but this is pretty much what it looks like removed...

[eva2000]

awesome stuff :)

[ThugsRook]

thx eva :)

...removing the IHS gave me an extra 10mhz core :cool:

[ThugsRook]

hehe~ just FYI:

Serious Sam was the first game/benchmark to crash during my testing, not Doom III ;)

[dbwillis]

nice to see some improvement...10 on core...let use know what it settles at with no crashes !

I'd like to see that done on the NV40. :yikes:

LOL! you know i dont screw around with ego threads db ;)

extra 10mhz ~ 100% stable in all benchmarks & games, including Serious Sam, Serious Sam SE, Quake III Extreme, 3DM2k1, 3DM2k3, X-Isle Tech Demo, and Doom III for many many many hours on end.

Looks great thugsrook . . . . :rock: I just dont have the heart to try that on a $500 board. . :bonk:

[ThugsRook]

i cant say i blame you one bit Hawk ;)

but eventually you will get tired of the thermal thottling, and youll be searching for this thread AND the bios mod thread :mischeif: :D

my 5900 is over a year old already! :cool:

[ThugsRook]

...still running strong @ 520x950, no problems at all :thumbs:

Probly dumb question but i'll ask just the same. What did u replace ihs with? :?: :hide:

[RotorHead]

With the IHS removed the heatsink will set right on the exposed core.

[BB_One]

Ha.....makes sense I knew it was a dumb question..must be late..lol.

heh...pulled one back from the dead!!! :o ...but thug how did you get the IHS off exactly mine isn't comong off to easy!!! .......seems no one wants this card(BFG5950U) so i will mod it and see how far i can push it till it flames out!!! :D

[ThugsRook]

razor blade or xacto knife under the IHS.
should slice thru it rather easily.
then just pry it off slowly and clean it up.

5900's are still very good cards, but newer games may be limited to 800res for smooth gameplay.
