Fan layout... suggestions??

[Monkeyspaz5000]

This is my case....

I currently have an intake fan (120mm rad in push pull) at the front and a 240 rad in the roof exhausting air.

My thoughts are this...

The air being brought into the case via the front fan will be warm due to passing through the rad. So the air getting pushed through the 240 rad in the roof will be warm air.

I'm not 100% sure if I can fit a rear fan inside the case due to the rad as I had to move the rad back a little to fit the recon fan controller in.

My options....

Leave as is and either have an exhaust fan at the rear - possible mounted externally.

Mount a rear fan as intake. Have the top rads exhausting and the front rad exhausting. This way all rads get the coolest air.

A portion of the rear fan will be blocked by the rad also.


Thoughts??......

I have no temp issues - just looking for the best option.

General give and take is air in the front and bottom, out the top and rear. Just follow the basic principle...

Yeah - well aware of that.. was just thinking out loud.

I can't squeeze a fan in the rear unless I have it mounted externally which I'm not to sure about tbh.

 

[Monkeyspaz5000]

To add the rear fan or not..... ? Mmm.

 

[OptimaLnrg]

what about those slim 12mm thick scythe fans?

 

[Monkeyspaz5000]

That would be spot on. Anything about 20mm or less would do.

OCUK sell them??

 

[Monkeyspaz5000]

Found some yate loon 20mm fans. That should do the job.

Just thinking outloud here.... why not have both radiators intake and let air exhaust where it will? CPU & GPU are on radiators so only cooling needed is mobo and HDD.. and radiator exhaust air temp should cool them just fine.

 

[Monkeyspaz5000]

Yeah... that's another option.

Possibly a better idea?? Then just have an exhast fan at the rear?

Fresh cold air coming in for both rads that way.

Like I said - temps are not an issue - just trying to suss out the best possible option here.

 

[Monkeyspaz5000]

If I was going to have all the rad fans as intakes and the rear fan as exhaust, the two on the 240rad would be pull instead of push.

 

[Monkeyspaz5000]

Thinking out loud here....

I think it would be better as suggested above to have both rads as intakes. That way both drawing cooler air in and having a rear fan as an exhaust.

If there is any performance decrease due to having the 240rad fans as pull instead of push, then I think the fact that I will be drawing cooler air through the 240 rad from the outside will balance this out in the long run, if not be better this way.

You wouldn't need an exhaust fan. I have one in my R2 but only because it give me airflows over Northbridge heatsinks.

 

[Monkeyspaz5000]

Rear exhaust fan won't hurt though - at least get that warm air out of the case a little quicker than it finding its own way out.

 

[doyll]

No, rear exhaust fan won't hurt airflow but will increase noise and if mounted outside not look as nice.

Really it's down to what you like.

i vote - both rads intake then an internal exhaust fan if it will fit, otherwise exhaust on the back.

That's what I'm going for.

I've ordered a slim yate loon (20mm) fan for exhaust

For anyone who finds this thread etc...

I have changed back to front rad intake and top rad exhaust.

Having both the rads as intakes was seriously warming up the inside of the case!

Not doubting you at all. But could you define how warm seriously warming up is?

10!
