EVGA GTX 260 55NM PCB (Ambient) Temperature Help

Hi all,

Ive got a EVGA GTX 260 55NM and there was a recent jump in temps so ive been looking at the PCB temp.

Is the PCB temp the same as your ambient temp?

I Dont really have a clue were these temps should be at, any help would be greatly appreciated! ;) 

Idle PCB Temp: 39-40 C (fan on auto or 40%)

Crysis Warhead Load PCB temp: 51C (GPU fan 100%) (every other fan in computer maxed out with fan controller)

IF these temps are ok, what else could cause a sudden jump in the core temps of you GPU?

My Sig Rig

Mobo: Gigabyte GA-X48-DS5
CPU: Intel Q9550 E0
Memory: Patriot PC8500 Viper Extreme Performance 2x2
GPU: EVGA GTX 260 55NM
PSU: PC Power and Cooling 750W Continuous 820W Peak
HDD: Western Digital Caviar Black 500GB
Case: Thermaltake Soprano RS 101 VG7000BWS

Those are good temps, especially under full load. What jumps in core temperature are we talking about? When do they occur? How hot does it get?

Well I think i have found out what causing the increase in temp in idle. The card must detect rhapsody (a music player) as 3d app and speed the cores up a little bit.
because when i open rhapsody the card runs a little hotter. and after i close it it cools back down to normal

I will have to do a GPU-Z log while playing Crysis Warhead to see the highest my temps get.

BTW i installed a another 120mm fan on the door to blow right on the card, and now my temps have dropped a great amount.

Idle PCB is now 36-37

Idle Core Temp is now 45-46

But my load temps show the biggest difference!

Also...

I have the Vanilla Version Overclocked to the SSC Cards Specifications.

I wouldn't run the fan speed at 100%...i mean really there isn't any reason to unless going from 60/70 to 100 makes a big difference....atleast lower it to 80 as any decent case should keep that card cool...

Although i have a horrible case cooling wise...so i doubt yours can be worse than mine

Ya, last night playing Crysis warhead for an hour or 2.

The highest temp the card hit was 61C (at 100% fan)

But my case fans were the cooler master 4 pack of 120mm, and they dont move squat for air.

Im assuming optimal load temps is 60-65 Degrees celcuis?

My GTX260 idles at 39c and runs 50-60c under load. You are fine.

To be honest, I wouldn't run your fan at 100% all the time because it is a mechanical part and therefore you are actually wearing it out more rapidly. I would suggest you lower the fan value to <80% which will help to keep it going in the future because your card is good up to about 75C under full load.

That was the reason i suggested the lower fan speed but most people just don't care since its covered in the warranty....my gtx 260 with an overclock of around 700mhz and up stays below 60c aslong as the fan speed is in the 70's...my 9800gtx+ stays way cooler...

Then again my room is always very hot and anytime i take my rigs to work they perform atleast 10c cooler under load...its ridiculous

Why do people assume that Case fans can run at 100% always but graphics cards fans don't?

If you are comfortable with the noise then run it at any speed you like, so far my 8800GT that I OC'd heavily has been a champ running at 70% fan speed, any higher than it gets annoying though, which is the main reason I haven't turned it up.

Hmmm unless your going to open your card and void the warranty to replace the fan you have to rma it...and thats if the card is under warranty in the first place...im sure you and everyone else are just dieing to find out how fun it must be to replace a gfx card fan :sweat: 

To be honest i would much rather replace the fan iv modded into the front of my case that runs at low RPM through an advanced cooling manifold then my not under warranty gpu fan :)

That *** right there will run you up to 99 cents and they may not include tape....high tech setup you betcha!

But you don't HAVE to replace them because they don't BREAK.

Suuure they don't....

Its not like it won't weaken it quicker over time either....

It will, but are you planning to use the computer for 20 years straight?

May 11, 2009 9:24:34 PM

I now run the fan at 70 - 75 % when gaming.

Thanks for all your help guys! :D
