GPU Cooling
« on: January 26, 2009, 06:39:13 PM »

Hi all, after months of immense GPU Tweaking I seem to have come to a big problem. All those tweaks have lead to increased heat output when Idle my GPU will do 40celcius but under load is goes to about 60celcius is there any thing I can do about this as cooling is the main thing i need to learn about on a PC  :lol:

Fit an internal fan of some sort?

A case fan would certainly help... maybe pop over to the CA forum and ask in the other hardware section - there are some pretty knowledgeable peeps over there.

Have a look at Zalman fans - which are supposedly the best for GPU cooling.

Heres some pics of a Zalman which was added to my graphics card on my old PC..
 which previously kept overheating to the point that it would cause the PC would reboot until it was added.




Original RAdeon 9800XT.  Had already been replaced under manufacturers warranty due to overheating, but still wasnt coping.

Thanks for that kitz I'll look at that brand you mentioned there maybe something cool enough to slay the fiery beast that is my GPU. I just hope if i install this right I can get on with tweaking  :D

EDIT* Seems to be quite difficult to find a cooling system for a 7300GS  :no:

When Medion produced that particular PC there was a big batch of faulty graphics cards at the time.
I had mine replaced twice.

Maplin Electronics used to do a good range in Zalman products, but not sure if they still do.

Yah mine was replaced the 1st time within warranty - the 2nd time it was just outside, but TBH (at the time it was a fairly hefty graphics card) the tiny fan and heat sink just wasnt sufficient to keep the card cool if you stressed it out.

Decided it would be quicker and easier to do the mod.


Cant recall where I got mine from now - chris got it for me..  but I'm pretty sure it was from quietpc.com.
I think Amazon also sell them.

The last cooler I purchased was from Eclipse Computers at Coventry.

60degrees is nothing for a GPU.  my 8600gt runs at 90 degs sometimes which is within acceptable running temp.

do u get any artifacts on the screen when stressing it??

I dont see any artifacts when at 60celcius but even that is with Overclock and some other stuff   :)

Tweaking the GPU performance will result in higher temperatures. I do not think 60 C is anything to worry about, especially as your current card is still performing without any noticeable problems.
For a lower temperature, you have two choices.............improve the fan cooling or use water cooling.
As water cooling is expensive, then that leaves the fan. A dedicated graphics fan exhausting directly from the card to outside the case will be the preferred choice. A copper cooler and decent case fan may be an alternative.
Some choices here.

Passive cooling will dissipate the heat to the inside of the case. Ensure you have adequate case cooling........a front and rear fan for a good through air flow ventilation. No good having passive cooling if the interior of the case is stuck at around 60-80 C, but I am sure you realise that.

Of course  :D Hot air + hot air = simply heat  ;)  The casing of my PC is mostly designed for ventilation as the front, right and rear all have vents and I have a small extra exhaust round the back for  when the system temps rise above 80celcius as there is no point in turning that on as I would be removing the air too fast that it doesn't have time to cool anything  :) . See a day of examining my system and learning the fundamentals of PC cooling  ;)
