Advice on cooling setup

[JackHinton]

Recently with the hot weather in the UK i have been experiencing high cpu and gpu temperatures under load. I had a look to see the current fan configuration in my pc (brought it pre built) to find that there is only 1 intake fan and no exhaust fans. I am purchasing 3 more fans now but don't know what to set each of them to (intake or exhaust) in each position. I am going to attach a photoshop'd image of a pc i found online showing the available fan positions. Green line means there are already fans there and the red ones are all the available places where fans can go. The current fans (shown in green) are both pulling from right to left. Please reply saying what fan should be intake or exhaust for example : Fan 3 = intake, Fan 5 = exhaust etc. I have heard it is best to have more intake than exhaust or an equal amount. THIS ISN'T MY PC, JUST ONE I FOUND ON THE INTERNET FOR A VISUAL REPRESENTATION

My idea was to have fan 1 as intake along with fan 3, then have fan 4 and 5 as exhausts as the cool air is brought into the cpu fan from the top and bottom right and the hot air is exhausted out the top and the back. The thing that made me doubt this was that there may be hot air being taken in from the top where the hot air was exhausted. I might be wrong or there is a better way of doing it.

In general it is better to have more intake than exhaust, especially considering some GPU's will exhaust all or some of their air out the back as well.
Personally I would put another 1 in the front and probably not bother with the others and leave 5 as an exhaust.

Try it, then make 3 an exhaust and see if the CPU temperatures are better or worse.
Nothing wrong with negative air pressure, but you may have to clean out your PC of dust every so often.

I would have done that but my case doesnt allow for another fan in the front, kinda stupid if you ask me, only having one front fan.

That's a phanteks enthoo pro unless I'm mistaken. You have space for two large front 140 mm fans. I have the same one. I moved that front fan to position 4 as exhaust, to aid fan 5, and got a set of good aftermarket fans, something with a bit of power for the front. Noctua's fans are praised as best quality though they're pricey so only if you can afford them but you have plenty of cheaper options too. Do not put anything on 3. That would just suck the exhaust air of 4 back into the case, not to mention probably mess up the airflow but it won't hurt to test it out if you like, see what the temps are for yourself. Alternatively, you can get a liquid aio cooler for the cpu and then just stick it to the front or up top.

For some reason i didn't think about just swapping them around and testing temps to find the best option. Thanks, lol.

Thanks for the help, i should have made it clearer that this isn't my pc, i was using it for demonstration. Sorry about that, but thanks

Ah never mind then Then it's a matter of experimentation. Fans are relatively cheap, buy an extra one or two, and play around with it.

Thanks, you still gave me some useful info.
