XFX 6600GT Cooling

[bravo_unreal]

hi guys, i got the new version with the "improved heatsink" <<<what a joke. im idleing at 45degrees and when i play games the graphics go all choppy. I lowered the memory speed to 900 (standard 1ghz) and it was still choppy. also before anyone asks ive got a 400w powersupply, 3ghz p4 and a lot o cooling.

help??

would prefer a new fan/heatsink if anyone knows where i can get one

Hi, how do you know its gpu overheating, that temps ok.

[mikalcarbine257]

Your probably pushing the card to hard (settings like filtering and such). Try dropping the settings and see if that helps at all, those temps are fine, even at 55 or 60 I don't think it would create stuttering

I didnt realise he was o/c tha card, never said.

Are you o/c that gpu or that normal out the box speeds causing probs ?

[bravo_unreal]

those are the standard speeds 500mhz core and 1.00ghz memory.

if the heat isnt the problem then what is??

It's possible that you have your AF and/or AA set to high, and/or you have the detail/res set to high in the game, thus your framerate drops below 30, thus the image appears choppy.

I bought a XFX 6600GT AGP in mid december, it came with the "improved heatsink" as well. It worked well for a week or so, until I started getting horrible slowdowns in games, severe image corruption and finally lockups.

So I checked the temps on the card via the nVidia panel, and I was surprised to see 70-80°C idle and up to 115°C while playing any game. I opened up the case hoping it would lower the GPU temp, but temps went down only a coupe degrees, even being in an air conditined room. The "Ambient Temperature" sensor was not working, as it said "unavailable".

The card finally fried and I sent it back to XFX for replacement. A couple weeks later I got my "new" card, and it has the nVidia reference heatsink on, which is much quieter and looks nicer. With this card temp are ~50°C idle, and go up to ~80°C under load (It's summer here, room temp during the day is around 35-40°C).

I did some research regarding 6600GT cooling issues, and seems there is a major design flaw in how the heatsink is attached to the GPU. There are a lot, A LOT of people reporting fried 6600GT cards of all brans, but mostly XFX (maybe because XFX's are the most popular).

Take a look at the card sideways, and you'll probably notice that the heatsink is not making full contact with the GPU. I recommend you to request an RMA, and check the replacement card for the same defect before installing it. After installing it, monitor temperatures for a couple of days to check it works as it should.

it sounds like your demanding it too hard with resolution/details/fsaa and filtering, overheating would shut the card off and they are built to 120*C anyway

I have 2 XFX6600GT's in Sli mode, and they are both idle @: core 1 : 56 degrees, core 2 : 58 degrees, without any oc-ing going on. both cards run fine, no stuttering.

i have a XFX 6600AGP card and i have idle around 58 and maximum of 85 while playing UNDGND2.....i dont know wat is the problem but even when i reduced the room temprature to 10*c with help of two AC's the temps where same just a 1 or 2*c reduced i don't know wat is the problem is it faulty sensor or faulty HSF....please help i don't wat to burn my card......
