Case cooling

post #1 of 27
Thread Starter 
Right now I've got my rig set up in a Lian-Li PC-K62. I've got all the original fans set up and I've been looking around thinking maybe it's not the best setup.

What I'm looking into is what's the best way to set up my fans for the best air flow and also if I should look into getting some aftermarket fans to replace them. I've seen posted that having two exhaust fans on top can actually hurt air flow as well as having the two exhaust fans perpendicular to each other.

Any suggestions on new case fans and different set ups?

If you have the one 140mm intake, one 120mm exhaust, and two 140mm exhaust that's about as good as you can do with that many fans, (Btw test it out, change the top two to intake or one intake and one exhaust and see which one is better because the configuration differs from case to case) but what I would recommend is to upgrade those fans to this for high performance, but a little louder (can be perfect with a fan controller) or this for medium to high performance, but nearly silent at full speed, so it can be left on 24/7. Also use those fans for the 140mm fan slots, unless you want this which is a pretty pricey fan but is 140mm and pushes a decent amount of air VERY silently. Another option is to, if you don't use more than a couple 5.25" drive bays, put some extra 120mm fans there and jerry-rig them on so you can have 2-3 front intakes.

Some members have found that by making the front top fan an intake and blocking the rear top fan, they can decrease their CPU temps by up to 5*C.
Just make sure that your CPU cooler airflow is from front to back, and that you filter that top intake fan.

This arrangement works fine. Here's a diagram of mine:

You have a much better case than mine, but note that I have removed my rear grill so I can do without a rear fan. You are lucky you don't have a grill on top.

For my K62, my top front fan is a intake and the back top fan is an exhaust.
Also, I changed the stock 140mm fans to Yate Loons High Speed (3); overkill. If you are going to upgrade your 140mm fans, you should get the Med speed ver. At 1400rpm+ there's noticeable noise level.

Once you make that top front fan as an intake, make sure you get a thin aluminum fan filter to keep your case a bit clean.

Nice setup.

I'm sure you're temps are great. You'd probably improve cooling on your mb and gpu (and maybe the cpu) if you removed the rear grill and just let the air flow out. It'd be quieter too.

Try with both intake vs front intake and rear blocked off. Compare temps.

I apologize for pulling this from so far back, but I don't want to just make another thread. :3

A few more questions:

1. Would blocking the back top fan be better than also using it as intake?
2. Is removing the exhaust fan at the back really that helpful?
3. I'm running my HR-02 passively, would this change anything.
4. Is this what I should be looking for in a fan filter or does it matter?
5. Fan controllers. Useful? Worth it? What should I look for in a fan controller?
