1900XT votage regulator temps

[Fistandantilis]

I noticed that the voltage regulator on my 1900XT gets hot, it ussually gets as hot as the core on my card I have seen it is high as 80c. The card is not giving any sort of errors, no artifacts or VPU recoveries.
Do you guys think that this is a bit high? is it a bad idea to take the sink off the regulators and add as5?

thanks

as far as as5 is concerned, I did that to my 6800 GT and it lowered the temp a little

If you can...change the stock cooler and put a fan that blows right across the regulators.

Does the stock cooler blow air out of the case?? If it does then forget the aftermarket cooler and just add a small fan that will blow on the regulators.

Before I added the fan, my regulators would also go to about 75 degrees. I then went to watercooling and added the fan and the regulators don't go above about 60 degrees anymore and that's when it's overclocked as per sig.

I connected the fan as a system fan on the motherboard. That way, the fan speeds up as the system temps go up, which happens when I play games.

Those voltage regulators run hot (the little devils under the red heatsink), so 80C is nothing to worry about.

cool I was thinking about that too. Cos mine hit 90C sometimes! O_O

Heh- well I'll take this bullet for 'ya.....Now don't answer this!!!!!

 

[LittleNemoNES]

ok

I'll possibly take the bullet here - but I want to point out - it appears that the red heatsink on the 1900's VRM is designed to have proper clearance only when the gray putty material is there - if you take that off and apply AS5, you might have to file the "feet" of the heatsink down in order to ensure contact.

I'm running my X1900 on water so I had to get some VRM cooling in order to OC - I mounted a 60x10mm quiet Delta fan onto the card over the VRM, added some MicroCool mini-sinks to the coil blocks. VRM temps max out in the low 60s now, with a 700/800 1.45 VGPU overclock applied - much better.
