Default My 8800gt gets damn hot- hardware</sensor defect ?

Hi Guys,

i use a 8800gt with the default cooler and default clock speeds.
I do not overclock the card.

The Problem i notice is, that while playing that card gets up to 92C !! , the slowdown threshold
is 100C.

While being in desktop the temp is already about 65C.

The cooler does not speed up much while playing. Its always about 30%.
Shouldn't the cooler go up to >60% when the card gets that hot ?

Should i return the card ?

Any advice would be helpful.

Thanks in advance,
Christian

Does it use stock cooling? When researching 8800GTs last January, I regularly saw reviews of cards (with stock cooling) pushing 90c under load. That was the main reason I went with a Gigabyte GV-NX88T512HP, which came with a Zalman cooler, I don't remember seeing it above 53c.

Both my 2 8800GT (G92) run at 80+ C while my 260 GTX goes up to 65C.

Of course the 8800GT have a stupid fan that blows air into the case while the 260GTX has a fan that takes another slot and blows air out of the case. This was also the case with 8800GTS (G90), it had the same 'good' fan blowing air out of the box.

In general I have found that the cooling system quality of 'cheap' cards is also cheap resulting in these high temperature numbers.

I guess not much you can do unless you change the cooling system.

Yeah, the card uses a stock cooler.

What i can not understand is the fact that the cooler does not run much faster when its that hot.
I nearly does not speed up while playing.

If i manually set the speed of the cooler to 100% (nvclock) the card gets damn loud
but the temperature falls.

I always thought the 8800gt would have a temperature sensor on it and would speed up the
cooler accordingly when the card gets hot..

But as you also read many reviews with such hot cards this seem to be a general problem of 8800gt with stock coolers...
