Stacking, Fans placements, Pressure

[whatthe_fuzz]

so im looking at this rad. its thick so i was thinking about have 6 fans on a 240mm rad. i would have 2 infront of my HDD cage then inside my HDD cage have the rad sandwhiched with 4 fans. so 6 fans in total. then i was curious about adding a 2nd rad behind my HDD cage. it would be serperate from the orignal rad and would have 2 of its own fans.

 

is this still considered stacking?

 

would i be able to have enough power to pull al the air through ~120mm total thickness rads with 8 fans? 

 

should i use 6 fans on the thick rad? 

 

thanks guys!

No that will waste your time and power 4 in pull, push, push/pull is fine

[M-ursu]

There is no point doing that, just use push pull, by adding more fans you will get about 0.00000000000000000121ºc improvement.

i didnt know if the thickness of the radiator would slow airflow drastically.

 

what about adding a second rad?

There is lot more sense, i would suggest you to do that.

I mean behind the harddrive cage :p

If you can fit radiator there, then great!

The FPI of a rad is far more important than thickness when it comes down to air restriction.

1 in the roof, 1 in the front is a staple of cooling for a reason...

its been proven (on overclockers forum i think) that having 1 radiator infront of another makes no sence, passing hot air from 1 to another doesnt help, and beyond having a super thick one doesnt help either, this is because of air saturation, the more heat the air absorbs the less it wants to absorb i.e your temps dont improve.

push/pull will also only improve things if the fin density is dense enough to restrict the airflow from the fans to the point that performance is lost compared to a less densely thinned radiator, in that case push/pull has an advantage, but this comes down to how dense the rad is, what fans your using, what rpm those fans are at and this all comes down (though not allot) to what cpu block you're using..

like allot of things its a mixture of everything you put it all coming together.

I could but what I meant was a rad in the hddcage the another rad on the outside of the hdd cage. about 40mm apart

so if its thick with high fin density, will 4fans be enough?

im going to ghetto rig a 140mm thin rad on the top. I really dont have room at the top of my case so im trying to squeeze as much cooling as I can out of the front intake

As long as you're ghetto rigging a fan in the top, might as well ghetto rig a 180 rad up there

Staking fans will increase static pressure meaning you can run them on slower to achieve equal static pressure as if you were using less fans running faster. May be a tad quieter, though adding extra fans will add noise.

 

Practicality and temp differences will be pretty negligible though.

 

Those Alphakool rads are not that restrictive, push/pull even on lower RPM will keep your system cool enough. IMO water cooling is about looks and silence. I'd rather have a CPU hit 70C under load and the system be silent than the CPU be cooler but sound like a jet. As long as you hit the OC you want CPU temps don't matter (under recommended temps of course), you're won't be getting more performance by running the CPU cooler.

i cant fit a 180mm either :/ if there was such a thing as 160 i would be good but unfortunately not.

my gpu gets pretty hot so wc would be worth it.  

 

good info btw :D
