How would you observe VRM/VRAM temps?

post #1 of 17
Thread Starter 
Will be converting my ref. HD 6950 2GB card to an Antec Kuhler cooler from stock cooler very soon.

In addition, I'm going to be putting on a Gelid Icy Vision Enhancement for the mosfets & whatnot.

http://www.gelidsolutions.com/products/index.php?lid=1&cid=13&id=62

I'd like to make sure I did it right so I can 'just know'.

Is this possible w/o manually putting on a temp. probe?

If the card itself doesn't have a sensor, and you don't want to shell out for an IR thermometer or a temp probe, just use your fingers on the back of the PCB. Most any GPU VRM will get uncomfortably hot under load, but if you can't hold your finger there, it's probably too hot.

What I did was get one these: http://www.dealextreme.com/p/digital-lcd-humidity-hygrometer-and-thermometer-14709

 

Taped the sensor to the PCB not touching any of the parts and just the PCB.

I'm assuming it'd be the VREG?

This is the temps with the stock cooler and other stuff on.
What would be the max I should be hitting until I should start worrying?

You're safe on the vreg till 120°c, mine peak at 115°c with no performance issues.
Of course the cooler the better, and fyi the OEM cooler is just about as good as it gets for controlling vreg temps.

But man your idles are high, running dual monitors I assume?

That's a negator on the dual monitors.
I always knew my idles were high, main reason why I'm switching to a CLC, in hopes of improving the idle temps (and noise).

I think it's my case, Antec P182, lowest airflow ever.

Going to be upgrading case when I move towards college, another year to go.

As far as the VRAMs, if they do overheat, what do I risk?
Just artifacting or actual board buuurrrn? rolleyes.gif

Yeah, they do run way to hot with dual monitors. I had to stop because I didn't want to shorten the lifespan of my card for that extra 1024x768 pixels. But on a tempature note, I fried a tf3 with a messed up cooler @ 1.3 volts, +20 mem volts, and +20 aux volts @ 93C core, ~100C temp 2, and ~110C temp 3. So depending on the voltage depends on how hot you can run it. Personally, I would now never run a card over 90C for any reason.

I remember, first day I got the card, dual monitor'd with two 22"s.

Instantly hit 65 in my case.

Your card isn't down clocking, hmm..
Should be at 250/150/.89v when idle.
I wouldn't worry about the memory, blown down coolers work well for cooling the memory.

Temps 2 and 3 are on die, I'm talking about the vreg temps.
But yeah I don't like to see >80°c on the die temps.

Hmm. Did not know those were all die temps. But, why is there so much variation in die temps?
