Looking for solutions on optimizing my computer cooling.

Celso_Patiri · Dec 29, 2015

Hello there, i have a couple of basic question regarding computer cooling, first of all, is there any danger on using an air conditioning directly inside the desktop? and what is the right way to do it?
i have an Xtrike Conqueror computer case with 5x 120mm CoolerMaster fans, 2 on the front, 2 on the top and 1 behind the case. My idea was to setup the 2 front fans blowing air inside the case, the 2 top fans blowing air outwards and the back fan blowing air inwards with a tube conected to it and with my air conditioner (the psu fan, wich is on the lower part of the case blows air outwards).
Is that good and safe? thanks for the help and sorry for any english mistakes.

In case it helps, here is my rig
FX 8320 3.5ghz 16mb CPU
MSI R9 380 4gb GPU
8GB RAM HyperX 1600w
Gygabyte Ga-78lmt-usb3 Motherboard
1TB Seagate 7200rpm HD
700W CoolerMaster Bronze 80 plus PSU
X-Trike Conqueror Case
(Intend on investing on a 120gb SSD soon)

The way I look at your system, it not at all a fan or airflow problem if your system is overheating. the FX 83xx are producing quite some heat and if your motherboard cannot "absorb" that heat then the whole system will runn at a big temperature. I suspect your motherboard is getting quite hot with that 8 core CPU. You should really look at the 970 chipset or even the 99FX chipset, they will handle alot better your CPU.

I haven´t built my system yet, this will be my first ever pc built by myself, so i don´t no how it´ll do in terms of temperature, but i have that AC right on the side of my desk, so if that idea i had of using a AC tube conected to the back of my desktop is safe and don´t harm any components, i will do it because it´ll be quite easy.
So what do you think, is it safe? and what is the right way to do it?
thanks a lot

I do not think it's safe at all. Even a good airflow inside the case can still get you temperatures of up to 40Celcius. A really cold tube of air at the back, combinet with some hot air can produce some " sweat " at the end of the tube and will only fall down inside your PC.

Yeah, that was the type of stuff i was fearing, i'll search more deeply into the matter but for now i'll trust in you
thanks a lot.
just another thing, buying a new motherboard isin´t really an option for me, what do you recommend to optimize the cooling? and wich fan setup do you recommend? there are 5 120mm fan, 2 on the top, 2 on the front and 1 on the back.
i´m talking about like, wich i put blowing air inwards/outwards the case.

Celso_Patiri :

2 intake fans at front
1 exhaust at rear
1 exhaust top should be more than enough

You basically whant to recirculate air inside the case so ideally you should have 2 intake+2 exhaust.

But there's also the power supply wich will be exausting at the bottom, so like that i would have 3 exaust and 2 intakes, and what about the second fan at the top? should i just dont use it?

You can use the second fan at the top no problem. 1 fan will not make much of a difference in temperature just on a noise level.

But like that i'll only have 2 intake fans with 3 or 4 exaust, isin't that bad for pressure and stuff? using the rear as intake isin't an option? or maybe the 4 at the front/top as intake (or maybe just 1 at the top as you sujested) and the rear one + the psu fan as exaust?

The PSU fan is for intake and is only meant to cool the PSU not the entire case so you can scratch that one out. 2 intake fans at front and 1exh rear+1 exh top should be enough. You can put 2 exh at top no problem and it wont make a difference other than noise.

Ok man, thanks a lot for all the help, i'll use both fans at the top for aesthetic purposes with the LEDs.
that's about it, thanks.

No problem pal, glad I could help

The thing to remember is air flow through the case. The best air cooler won't work well is the air isn't moved out of the case. My solution for my Dell XPS8700 i7 4790k running BOINC 24/7:
- Noctua NH L12 chip cooler with the bottom fan pwm and the top fan running at full speed
- Noctua 90mm fan at the front of the case running at full speed
- 50mm fan at the exterior exhaust port of the power supply running at full speed
- 60mm at the case exhaust port running pwm.

My temps run in the high 50s and low 60s.
