Case fan questions

[Opunaesala]

My new computer is in a Phanteks Eclipse p400 case.  I have the 120mm intake fan and 120mm exhaust fan it came with, and I supplemented it with a 140mm intake fan in the front panel and a 140mm exhaust fan up top.  My temps are fine, but is there any benefit to putting another exhaust fan up top?  It has space for 2 and currently the front most space is empty.  Would it improve airflow to put another up there, or will it not see much benefit over leaving it open air?

What are your specs and temps?

If you already have sufficient airflow, adding more fans won't make much of a difference. Otherwise, adding more can help cooling or allow for sufficient cooling with lower rpm and noise.

MSI B350M Bazooka Motherboard, Ryzen 7 1700x, a coolermaster CPU air cooler (unsure of exact model), 16GB RAM at 2933, GTX 1070.  At idle it is in the low 30's C, just browsing or playing a non demanding game like Slay The Spire, it is in the low 40's.  I haven't checked temps after playing something for a while, but I've haven't had problems and the air coming out of it is always cool.

 

If having an extra exhaust is even slightly beneficial, I might do it, decent fans are pretty cheap.

Those are very low temps. I'd recommend using a stress test like Unigine Heaven and OCCT to see a worse case scenario but you probably have no cooling issues and adding a top exhaust probably wouldn't make much if any difference.

Thanks!  New to this board, so thank you for the tip as well.  I'll try out some stress tests when I get time tomorrow, and see what it looks like.

I have three front 140mm intake fans and ramping them up to 100% seems to offer no decrease in temps, perhaps it would over a longer period of time but I'd say it's probably not worth the extra fans if you have sufficient airflow.
