I'm trying to squeeze more power out of my 630i. I recently upgraded from two 9800GT's to a single GTX 560 Ti and from 4 GB to 8 GB RAM. I also over clocked the CPU from 2.4 to 3.0 GHz.

I am trying to reduce the internal temp of the box, I have modified my fan speeds for the case already and I have decent temps on my CPU. The temps range from 35-40 at idle and during stress tests, at 100% utilization I am about 60c max.

I'm looking for a good product to add to the 630i to exhaust some more heat. I'm more curious about fans for the PCI slots, something easy I can slap in.

Any thoughts or comments?

Did you already add an exhaust fan? I'm using a 120mm fan with a 92mm to 120mm adapter.

*Old pic but still using the rear exhaust fan with my new setup

But by far the biggest cooling improvement gain I had was adding a window to the side panel with a 120mm intake fan blowing right onto the gpu and cpu. Big project though =/

Yeah that's what I'm looking for, something to push the air out from the CPU at the bottom. Can you provide some more detail as to how you made that work?

I'm more on the software side of IT, programming etc...so the hardware isnt as clear to me but I can do it if I see it :D.

I found some very cheap products on newegg, $7.00~ for a single slot PCI fan. I was thinking one at the top by the power supply to suck any hot air that has risen. However, i do love that fan you have at the bottom. Thats where most of the heat is, memory bank and CPU.

I've tried a couple of those PCI fans in the past and they were junk. It has been several years, so maybe there is something better out there now, but I'd be cautious.

Ya I've used a couple different PCI coolers and never noticed a difference in temps so I don't use them anymore either.

I actually have everything in place with zip ties. If you look at the rear of the case you will see holes for a 92mm fan. Some members just installed a 92mm fan there with no problem. Searching this forum will find you a couple threads on the exact fans used. In my case I have a GELID 120mm fan zip tied to the 92mm to 120mm adapter (linked in my first post) and plugged into the 3pin header on the rear light bar.

EZPZ. Very cost effecient cooling solution.

Thanks gents.

You went with the 120mm because it moves more air than the 92mm, I am assuming? i know Nvidia ESA has a fan control option for the mobo, can I control the speeds through these controls?

I am looking into this, this is very simple. Thank you again!

Looking around in my IT closet, heh, I found me a 120mm fan that is rated at 133.79 CFM. Is that overkill?

:shock: WOW how loud is it?

Yup. 120 > 92. And I liked the uniformity of having only 120mm fans in my case. If you have a nice quality quiet fan with 3 pin connector it will run at 100% all the time. That's how mine are setup and it's near silent.

I have to test it still, most of our workstations are small form factor and we don't have 4 pin molex connectors. I'll test it out tonight at home. This is from one of our old servers, so I'm sure it sounds like a jet engine >.>

That fan is super loud and it does push a lot of air out of the case. I jerry rigged that fan in the bottom of my case, simply strapping it to the back using zip ties. I can feel a huge difference from the front of the case, the air pulling in and then the air pushing out the back.

I ran some tests using Prime95, my idle temps were about 3-5 degrees celcius lower than before and at high load the difference was only 1 or 2 degrees. The biggest difference was when the tests were changing, the temps would drop much faster. I guess the only difference this made was the overall temperature in the case.

I ordered that converter, so we will see if that improves anything.

Nice nice. Proper testing ftw.

So I went out and got a converter for a 120 to a 80/92mm fan. It works great however, I feel reverse air flow between the CPU and the fan. The fan is facing the correct way, I can feel exhaust air coming out from the outside of the case.

If you look at the arrow on the CPU, I feel air going the opposite direction. I can only assume this is because I am pushing 133 CFM through the converter?

So I noticed several 4 pin connectors on the mobo by the back exhaust area, can I use these to power a fan? I want to try a new fan but its a small 3 pin, I don't have a converter for a 4 pin molex.

Yup. No problemo. You can plug a 3pin into a 4pin header, it will just run at 100% all the time.
