What type of air cooling for me?

post #1 of 12
Thread Starter 
Ok so i'm looking to my future upgrades as I kick my computer into top gear to be used on a professional level it must be fast.

At the moment i'm researching the air cooling portion of the case which touches on water cooling and case choice also.

What I dont understand is why in a case there isn't either full front intake (maybe 3-4 x 140mm intake fans) and full rear exhaust (3-4 x 140mm intake fans) and instantly we come across a problem! we cant have all those fans at the back because we have all the motherboard cables and such there!

So what about that system rotated 90 degrees so we end up with 4 intake fans on the base of the case and 4 fans sucking out the top? This is a case I could dig and have been looking for to no avail. If you know one let me know

But is there a flaw in my thinking? What im trying to do it rather than have an intake in the the front and rear and side and exhaust out the back and top (which seems messy) have a single lane or channel of airflow right across the board and throughout the entire case. Heat rises so I assume the case with the airflow upwards would be better?

Next note I should make is the system has only SSD's so dont worry about HDD space cables or temp from them. Just set up an old file server with my hard drives.

So what i'd ideally like is something I can suck in 4 x 140mm intake fans on the base of the case and put 8 fans on a 4x140mm radiator in push pull in the ceiling of the case.

Can it be done with what we have to offer on the market? is it a bad idea? let me know

Well, the only cases set up with the rotated layout are the Silverstone RV02/03 and FT02/03, I have the RV02, and it's brilliant. 3x180mm fans on intake and 1x120mm fan on exhaust. Balanced airflow isn't as great as you'd think it is. Usually either negative pressure (more exhaust than intake) or positive pressure (lots of intake,. only a little exhaust) is notably better for temperatures.
With positive pressure, you have a lot of air pushed into the case, which then escapes out through cracks and vents, and pushes its' way into the GPU's fan as well. Positive pressure is great for dust control, as you can filter your intakes and be pretty sure no dust will sneak in through other ways.

Ok so im a bit confused.

I'm asking what type of airflow would be better:
1: bottom of case intake and top of case exhaust
2: front of case intake and rear of case exhaust

and how those 2 flows compare to what to me seems like a confused airflow of the conventional front+bottom+side intake and top+rear exhaust.

Also i'd like to get a case that would fit a 4 fan rad inside the case but i'm not sure if having a multi loop setup means multi radiators or you can put all loops through the huge radiator and the pros and cons of that...

See how this is all a very confusing thing for me haha there is just too much to know!

In general you intake cool air from the bottom, because cool air falls. You're exhaust would be up top, because hot air rises.

EDIT: As far as whether or not the fan is on the front or bottom, it doesn't matter too much, some people prefer the intake fans on the front because you don't have to worry about dust as much as if they were on the bottom, sucking dust off the floor, but in reality, the extra two inches the fan is off the ground, when its mounted on the front, wouldn't really affect temps at all, as long as the intake fan is towards the bottom of the case, and the exhaust towards the top, you'll be all right.

As for the case, the only case I know of that I'm positive can fit a 480 rad internally is the rocketfish, when modded. I think the 800D can, and I believe the Silverstone TJ07 can as well, you'd however still need to mod the cases. And for two seperate loops I'd much rather have 2 240's than one 480.

A better option would be something like the CM690 II, it has space for a 240 up top and another 240 at the bottom. It is also much cheaper than the aforementioned cases.

@ Craiga35

Thanks a lot!

Ok so in picking a case would it be first best for me to figure out how many loops and radiators I would need? Because I have heard that triple loop is probably the best? would I therefore need 3 radiators and have to get a case that somehow fits 3 radiators?

Well, what are you looking to cool, one decent loop should be ok for a GPU/CPU combo, and it would be great if you utilised two rads in the same loop.

For example, your setup could look something like this:
Pump -> Rad -> CPU -> Rad -> GPU -> Res -> Pump

You could also do two single loops, but it would require two pumps.(not necessarily a bad thing)

Pump1 -> Rad -> CPU -> Res -> Pump1
Pump2 -> Rad -> GPU -> Res -> Pump2

Ok well im looking for future proofing what i'm trying to do is make a plan for the best build and set a progressive pathway to get there upgrade by upgrade. So I want to allow to watercool everything. cpu, gpu's, motherboard, ram... that's all I know of with my limited knowledge at this point. Is there a sensible maximum on how many loops one would have? do you need multiple loops or can you build everything into one loop with multiple pumps and rads?

This is becoming a watercooling thread...
post #10 of 12
I have only watercooled one machine, but from what I have learned off of this forum, you only need one pump per loop. I would say max of one loop for your GPU(s) and one loop for your CPU and mobo. If you MUST WC your RAM, throw it on your GPU. I think that would be more show though.. idk if it really gets that hot..
