Shoudl i install an intake fan or exhaust fan?

trying to get my system cool as my gpu gets pretty hot and subsequently the other components seem to aswell.

i ran the unigine valley benchmark for 10minutes. my gpu hovered at 78C with 95% fan speed (3400rpm ish)

before running the test my motherboard temp was 28C
after the test the motherboard was 35C
and temps for all components had risen along the same amount (ssds, mechanical drives)

given that there seems to be quite a lot of hot air hanging around inside, should i use the 80mm side vent to exhaust heat out?

the vent is located on the side panel, opposite the cpu, above the gpu (gpu is right in the bottom of the case)


my system has a rear 92mm noctua a9 exhaust fan. running at 90% fan speed constantly.
cpu i7 7700 stock cooler. stock clock
gpu asus gtx1060 dual oc
16gb ddr4 2133
psu corsair tx750

  1. Those temps look pretty okish to me maybe a tad on the higher side. Running a stress test, you cannot expect your temps to remain as during idle. There are bound to be spikes, but as long as they are within safe limits, it shouldnt be a problem. Having said that, your side fan should be intake. Remember, hot air rises upwards, and thats why the rear fan is always placed high up on the case by manufacturers. Front, side and bottom are always intake, where as rear and topside are always exhaust... http://cdn.overclock.net/4/4e/459x459px-LL-4e8a494d_B__MG_8156.jpg.jpeg

  2. You'd get better airflow thru the case if you could mount the 2nd fan in the front (low) as opposed to the side. I would make it an intake.

  3. heres a pic of the inside of the case, and one of how much clearance the gpu has.

    what are my options in this case?

    would a modular psu help me out by getting rid of unwanted wires?

    would the front fan even help the gpu as its so low?


    @hellfire13, yeah the temps are ok. BUT remember the gpu fan speed is 95% whilst struggling to maintain those temps for only 10minutes or so.
    forza horizon 3 gets the same temps in a similar timeframe, so its not just the benchmark thats heating the gpu.
    gtx1060's should get those temps while only using maybe 60%

  4. Wires have minimal effect in obstruction. Maybe worst case scenarios.
    What case do you have. The side fan is worth a try. Fans are pretty inexpensive anyway. Wont hurt. Better to add both in front and side as intake.

    I see what you're saying by the GPU being low !
    A fan mounted in front/low as intake would definitely help. At least air would be headed to the starving GPU.
    I'd also rig up something to get the SSD out of the way.

  6. the case is some generic matx from zoostorm in the uk. got the machine from them.
    it looked great until i tried fitting my gtx1060 in there :/

    the ssd was originally going to be mounted by sticking it to the bottom of the case with black eletrical tape, but as you can see (or not, because its quite dark) the bottom right of the case has a mass of sleeved black unused cables from the psu in there.

    thats why i asked if a modular psu would help by eliminating those wires (or most of them) so a fan could be fitted there unobstructed, and the wires wouldnt hit the fan blades
    obivously the ssd would then go flat rather than just hanging in there as it does now.

    i have a spare modular but im loathe to use it because others have said its very bad. its a ocz modxstream pro 550w. is it bad?? (its hardly ever been used)

    I have not seen the snap as its blocked in office. I will check it later, but i got the picture.
    OCZ is a Tier 5 unit... https://linustechtips.com/main/topic/631048-psu-tier-list-updated/ dont bother.
    Continue using the existing one. Tape the ssd to the bottom for better air flow. Add a fan to the front and side each. Also if you have vent at the top, add some exhausts there too.

    in the end i got a corsair rm650x modular psu
    that enabled me to free up the bottom front section of my case

    after fitting a noctua a9 fan in there temps are down 4c. not great but i doubt theres much else i can do tbh.
    short of spending more money on a new case, blower style gpu etc

  9. RMx is very good unit and it should give you better performance than the previous one. So your temps are down, thats great. Cheers...
