I've been using ATItools, "scan for artifacts" It tends to put the card under a large amount of calculations. I've also mapped the temps with Rivatuner. It seems to run a quite a bit cooler with this new HSF.Quote:

Yeah, Im just talking about the kit as a whole.. I think its pretty nice. but could use alittle extra washers or keep the hsf from moving in transport. but If you dont transport your card very much, no problems.Quote:

jeah i would also be interested in this because the thermal pads are higher as if you use some AS5 ... so if i put the Ati Silencer on my x1900xtx with the thermal pads still on the GDDR and AS5 only on the core.. does it fit correct than?

jes to confirm, you disabled the two services then raised the voltage manually?
what clock speeds? stock speed?
I kept the thermal pads on there, keep them attached to the heat sink, only thing to worry about is the part that touches the core. Let me take a picture of it for ya.Quote:

Now, when you pull the heat sink off of the card, it should basically look like that. Just leave the pads alone, toss some AS5 on the copper core, wipe it off the copper core, then toss some AS5 on the core on the graphics card, nice evenly spread. You should then beable to toss the heat sink back on the card, with lower temps.

you guys must be in really hot rooms or something, as5 stock cooler i idle at 38 and load at 62, overclocked of course
Just applied AS5 to my X800GTO2 with ATi Silencer; the temps were about the same, so I guess the stock thermal grease was good enough.
First - tested the Arctic Cooling X2 Accelero. Temps are ok, load was in the 60s with AS5 but the design is just dumb. It dumped all the hot air right into my chipset on the DFI Ultra-D and my temps on my chipset jumped about 15 deg C when the card was under load for awhile. Case temps rose too. The Accelero is just not well designed - do not bother with this cooler. This is the WORST design to come from Arctic Cooling in awhile. Give us the old design that dumped hot air outside of the Case.
Secondly - I have an X1900XTX and I changed the stock TIM from the ATI crap to AS5 and my temps dropped about 5 deg. arisythila if you are seeing 20 deg drop from the stock TIM to AS5, it's not just AS5 - the stock mounting must've been hosed man. There is no way, and I mean absolutely no way that just changing the TIM would drop temps 20 deg C. Even the company claims are a few degrees cooler than other TIMs. It's just thermal compound - my bet is that the stock cooler wasn't making good contact or than the TIM was just dried up muck, like it usually is.
Third - I gave up on air cooling the X1900XTX my load temps with VNF700 and a 120 blowing over it were still low 60's high 50's. I finally broke down and water cooled my whole rig. I have a Maze4 on my X1900XTX now, using max CCC overclock of 690 / 800 and my idle temps are 28c and load is 37 deg c. Unfortunately with todays video cards - thats how you cool them!! :p:
I got my HIS X1900XTX last week and have been pretty happy with the stock cooler. Using ATI Tool to adjust fan speeds, I'm at 43c w/ fan running at 55% at idle and 63c w/ fan running at 100% at load. These temps have been w/out taking off the hsf to apply AS5. The fan at 100% isn't too terrible plus I wear headphones when gaming, so I don't even notice it.
I haven thought about going w/ water coolinng but so far, I can't justify the upgrade.
Agreed. Not tried the Accelero, but the change from a 7800GT (pumping hot air to the DFI chipset etc) to a stock cooler X1900XT ended in around -15c on chipset and PWMIC.Quote:

I was just talking about my experiences with the X1900XTX. It was running pretty hot running stock @ 1.5v 680 / 827. Took the stock HSF off, cleaned everything up, applied a little AS5 on the core, put everything back together. Temps were surprizingly lower than before I messed around with everything. I've heard alot of people complain about temps, so I thought I would post about what I did to lower temps.I bet the stock cooler could do some good if it was lapped a bit, but I am pretty unsure why ATI did that. Im thinking that it creates more surface area for the cooling compound to make contact or something.Quote:

Ahhh, thats why you can run the fan at 100% you wear head phones.. I cant justify the use of head phones while gaming. the stock HSF is REAL loud... drives me insane. thats one of the reasons I updated the HSF to the VF-900. Got a nice temp drop, and I can run that fan at 100% without hearing it hardly. All I need :-)Quote:

I think your stock coolers mounting was screwed up and just the fact that you removed it and reinstalled it was what dropped your temps significantly, changing the TIM probably only accounted for a handful of degrees. Before everyone runs out for a tube of AS5 expecting a 20 deg drop - I just wanted to bring that fact to light. I did the same with my stock cooler and the AS5 didnt drop my temps more than 2 deg C - in fact I found the stock TIM to be decent.

They machine these grooves on purpose to avoid forming air bubbles between the core and the heatsink, which can cause a huge deficit in performance of cooling solution. Having baby-ass smooth HS bottom is only good if you applied the paste carefully and you know what you are doing.Quote:

It helps to keep my PWMIC and DFI Chipset much cooler, 10-15c than with a 7800GT w/ stock cooler. Any ideas on how to change the fan to the ATI stock cooler? I read somewhere in XS someone did it, I've searched but the search option doesn't work for me :confused: it hangs in "Waiting for xtremesystems.org" (FireFox 1.5.0.1)Quote:

Here's a review on the VF900-Cu... by me.

Got me 700/800 stable stock V in an Antec Super Lanboy, I'm not complaining! :)

I don't feel like doing that though. I might have to when summer rolls in.. meh.
Then I'd get spiders and the like in my PC and I'd go crazy.
