Cooling VRM?

[xnoobftw]

Is there anyway to cool my VRMs without replacing my Tri-X cooler on my 290x? Increasing fan speed doesnt stop it from hitting 95c... (Under Max OC, When it doesnt go max OC it hovers around 75c~)

[Godlygamer23]

I believe VRM can hit 128C.

But i saw somewhere that the safe tempts for VRM is around 95c...

What are your video card temps? What kind of airflow do you have in your case?

85-86c max load tempt (with max OC with default bios) 

3 intake 2 exhaust

 

 

Exhaust fan curves

 

 

My front 2 intakes are running 100% 100% of the time

my top intake is running with the CPU fan curve

 

My case has positive pressure 100% of the time

-snip-

Temps are fine and put the top 120 as an intake (trust me)

Both 120 as intake?

[Guest]

Both 120 as intake?

yeah

[xnoobftw]

yeah

But why? Wont there be an excess of stagnant air?

The exhaust fan is more powerful than the intakes and you want more cool air in the case

Huh? I have 2 sp120 performance for top and 1 sp120 quiet edition for front

The 1 intake sp120performance will cancel out the 1 exhaust sp120performance

Take an air conditioner, tape a tube on it, and strap that tube into your PC case. Congrats, your custom air cooling your whole PC.

If the stock cooler isnt doing well, that could be because it doesn't have to. The 290x is designed to run a bit hotter, with the reference hitting and staying right where yours is at. But the 290x is also designed to throttle back whenever not being used as heavily, or to underclock. So unless you get a AiO and strap it onto the card, or make a custom loop, theres nothing you can do about the OC temps.

You honestly don't need the top fans, you are congesting your airflow.

Although I am not familiar with that specific card and the cooling solution on it, I would suggest that you get this: http://www.superbiiz.com/detail.php?name=FAN-ICY290&c=FR&pid=899b1c72ed800aeb991b17c5bf318b00198d801f2c6600821daf26cb310cf13a&gclid=CIqWtvyVhcYCFc-PHwodKWUA1Q#

 

works pretty good from what I have read on the reviews. It is also available from newegg here: http://www.newegg.com/Product/Product.aspx?Item=N82E16835426042

 

Good luck!

The two top fans will be circulating used air.

Fans exhaust air at an angle which the intake will suck in and blow into the case at an angle, which will be exhausted at an angle and so on.

You're just creating a circle. Either have both as intake which is not a good idea as it will be fighting the hot air rising. They will keep hot air in the centre of the case until something disrupts it. Plus they will suck dust in that's free floating in the air.

Or have them both as exhausts.

 

!Don't go against the law of the universe that the almighty God has created!

 

 

About the VRM's. VRMs can normally go well past 95C. 125C sounds right.

But i've got em arldy... It's like 25 bucks a piece D:

But can i install that with the stock cooler on it? (tri x cooler)

Hmmm but i've already bought the fans.... I've tried all the possible configs for the fans above and this yields the best results + positive air pressure (my CPU cooler is effectively getting it's own fresh air now while the GPU's hot air is getting pushed towards the end of the chasis)

When i have both exhaust on the top side i dont feel any hot air going out from the front top fan (maybe because the CPU fan is blowing towards the rear of the chasis)

So i decided to flip it around so that my case have positive air pressure and more cold air going in.

So it is ok for me to keep my OC?

But are the temps safe?

Yes, it is safe.As long as the temps don't hit 100°C for longer then a few seconds, it will be fine.

D: I'll monitor the temps carefully then

This will give you a good idea of what the temps should be. Mark it as solved:)

Trying to feel something hot is not the correct way. Use a thermal thingy (the name has lost me. It has Mercury inside a tube).

If it's lower than your body temp then it's cold, if it's hotter than you then it's hot. If it's roughly the same temp as you then you will likely not feel anything but moving air.

 

I would say your OC is safe.

If you're ever worried than you can get some after market plates. They are normally used for Vram but can be used for anything as long as you use something non-conductive between them. They normally come with sticky pads. They don't need to be thick. A single piece of flat metal works wonders as it will give the VRMs more service area.

Thermometer?

 

Hmm but the VRM tempts are really quite horrifying tho...

I saw somewhere that it is better to keep em below 95c

If you can't keep temperatures below a certain threshold without modding, then you have to deal with it or perform some sort of mod. The 295X2 VRM runs much hotter than what you're experiencing.(per GPU)

Im afraid i donthave the tools for modding D:

Im thinking of getting a copper shim of some sorts and thermal gluing them to the VRMs

I would say do that. It's clearly bothering you. Get a copper plate or something and place it on there. Remember though, non conductive.

Non conductive paste may do the trick as it's pretty sticky on its own, but you may need something stronger depending what you decide.
