X1900 Temps

Hi, it seems some users are reporting load temps of around 80/90C and others 60/70C with the same card/coolers. Is there a reason for this as a 30C difference in load temps shouldn’t be possible even with high ambient temps..

I've had a X1900XTX since launch and can remember pretty much everyone at the time reporting 80/90C.. But now magically some users are reporting 30C reductions in temps... Why?

Are some of these shipping with dodgy sensors? have they been fixed? Altered to make people believe there temps are lower then they are not to alarm users ?

Thoughts??
 
In my experience it depends on what the BIOS is doing. I had a X1800 who's fan would only speed up when the core hit 90C, but others had cards where the fan ramped up much earlier to keep the core at about 60C.

I don't think thats the case, it doesnt matter what cooler users have X2/VF900, theres still almost a 30C difference in load temps between identical cards.
 
Different fan speeds, different coolers, diff ambient temps, general difference in the contact between core and HS.



I have a IceQ X1900XTX, at 50% fan speed stock load temps are 60C.

Overclocked to the max, at 50% load temps are 70C (709/838 @ 1.45V)

Old X1900XT, with stock type cooler was a fight to keep it under 70C, it needed 70% to do that.


usually 18% to 80C and 90 odd % at 85C IIRC.
 
The standard x1900 cards temps are around the 80-90's at default settings i think.

a lot of people have the HIS Cards which have great coolers on, also fan speeds are really low by default on all the x1900's and people ramp the fan speeds up in the cards bios or by ATT/ATI Tool/rivatuner
 
I have the C3D x1900XT and my load temps never go above 65c i have good airflow in my case though i guess it makes all the difference in temps..
 
I've used the omega drivers progs to set my HISx1900XT to hit 100% fan speed when the core goes over 50c, at idle its 43c or so and tbh I don't care about the noise
 
Ok, this is nothing to do with coolers guys, again there can be almost a 30C difference with the exact same cooler. Now I've tested both X2 and Vf900 all at 100% fanspeed andl the temps remained much the same. Except for the stock fan which can drop the temp allot at 100% but is noisey as hell so I refuse to believe anyone will use it like that.. I've tried two card X1900XTX and XT.

Ambiant temps do not make that much difference to load, at the most it might make 5C difference but 30C is pushing it.
 
Errrm. 10C ambient difference at 0.25C/W is a lot I think.


The VF-900 can't deal with the X1900 cards anyway, its been known for a while. The stock cooler probably has bad contact and bad paste etc. Try resitting it with AS5.


Its probably a combination of either bad contact, high ambient, dust, fan speeds etc.

Room temp is currently 16C here, fan speed is 81%, core temp is 57C.

Take that up to 25C, fan speed at 81% = about 65C, at 100% thats about 61C.

CR.
 
The aftermarket coolers are rubbish for the x1900 and id say the v900 is worse than stock :o

I guess the way people measure load is very varied aswell :)

Gaming for hours on css or bf2 and the core sits around 62, dark messiah and company of heroes its around 77 but 3dmarking its low 70's

Those temps are in a case probably 1/4 the size of your's aswell and on a pretty high overclock for air.
The HIS cooler/Artic silver and higher fan speeds make a huge difference

Thing with the HIS cards is u can run the fan fast cus its no where near as loud as the stock coolers

My load temps now are only about 5C different from mid summer.. Thats 30C+ ambient vs 16C ambient . So can the X2 not handle the X1900XTX either?

That doesn't send the hot air out the case, and I think is a very **** design.

All of the stock coolers etc send it away from the case, so only cool air is drawn into the fan.

I'd expect the temp of the air the GPU is sucking in to be around 30-40C, maybe higher...

Right basically everyone with low temps is using a HIS cooler or running the stock cooling at 100%?

LOL

Errrm, yes. The VF-900 can't cope with the heat output and the X2 thing is **** because it recycles heat.

The His Cooler is the best air cooler, period, the next is the X1950XTX cooler, then the stock X1900 cooler.

Only things that beat them are a ducted X2 (heat actually goes out and has a fresh air supply) or water/phase.

I have mine running at 70-100% so I can max out the clocks and minimise any unstability caused by heat.

There you go, thats the facts.

Rubbish. With the VF900 it runs cooler and quieter than stock. Even when the GFX is under heavy load it runs cooler than stock. Case temps have hardly increased at all.

I used the stock cooler for about 2 months, at idle mid to upper 40's, and maximum was around 85 degrees. With the VF900 low 40's at idle, and no higher than 70 under load. Even with the Zalman fan at 2500rpm it is still considerbly quieter than stock fan during 3d gaming (spins up to a loud whooshing/whining sound)

16c room temp? heating bust??
 
vf900cu is very much dependant on the case temps and how your case handles airflow. i put a antec super cyclone blower next to the vf900cu and temps dropped 5c on the gpu on load. now im gonna het a new case that has vents near the gfx card area and mount a side panel exhaust fan on it.
 
Cyber-mavs done it again, 2nd post instead of editing :rolleyes: :rolleyes: :rolleyes:

Yes, I have a 16C room temp. I leave the windows open. Im quite happy in this temp. I use the PCs to warm the room up.

300W from a X1900XTX and a C2D is enough....

Its been known for a while that a VF900 can barely cope with the heat from a X1900, esp when overclocked. The X2 recycles heat.

The his stock coolers and the X1950XTX cooler are better than the aftermarket. The aftermarket only beat the rubbish ATI stock cooler.
