More fans = more cooling? ....should I add an exhaust to air cooler?

surfnoob

Recently just picked up a Halo Hyper 212 Air Cooler in white and loving it.  She matches my build and case perfectly and seems to keep the temps down a good 8-10 degrees cooler than the stock AMD wraith cooler for my Ryzen 7 8700G.  After seeing this setup though it got me wondering : https://www.amazon.com/ALSEYE-M120D-Plus-CPU-Cooler/dp/B0CT8FF8PM/?_encoding=UTF8&pd_rd_w=wy3m9&content-id=amzn1.sym.b0f81224-c575-416a-93d9-20e612928432%3Aamzn1.symc.c7d845cb-4910-45f5-9826-0c6eb52c18fa&pf_rd_p=b0f81224-c575-416a-93d9-20e612928432&pf_rd_r=JR1A06H2H8H2T2282NGV&pd_rd_wg=TnQHi&pd_rd_r=7dc3a89a-fd91-47b3-b9f2-2e5eec3fd5dc&ref_=pd_hp_d_atf_ci_mcx_mr_ca_hp_atf_d&th=1 ....

 

....would adding an additional exhaust fan to the other side of the fin system bring even better cooling?  This should be a fairly easy add physically but would it really make a difference?  From what I see of the cooler above, there is one intake and one exhaust or would 2 intakes be better for heat dissipation?  

 

Given my temps now with good case are around 30 - 40C idling and 40-50C in games.  Do think it looks kind of cool though with two fans but if can bring the temps down a couple degrees it would be worth it.  Anyone have experience with this air flow type?

Your idle and gaming temperatures are very very good.  I wouldn't bother adding another fan.

It wouldn't be anything worth while in terms of performance, maybe a degree or two at most.

 

If you want to do it for aesthetic reasons, go for it!  It certainly wont make it worse 🙂

Just make sure the fan you add doesn't spin super slow compared to the one already on the cooler, so the air doesn't get 'blocked'

Its nothing I would worry about though, just mentioning it.

Thanks, didn't think about that but you're right as the speed of the first fan (only on there now) is controlled by CPU or at least using that connection and whatever speed it is.  The second one would be using a "sys" or system fan and set at that speed.  Wonder if there is a way to get a splitter so as to connect both fans to the CPU fan terminal.

You absolutely can get a splitter, thats how most of it not all large dual tower / dual fan aircoolers do it.

Just a simple fan splitter like this.  It doesn't break the bank either, resonable price.

Going Push/Pull has diminishing returns but does perform superior to just Push or just Pull for fan setups, especially on AIOs, on air coolers I don't know if it would have as good of an effect, because I haven't had an air cooler since the stone age (my last CPU air cooler was literally on a socket 478 Intel Pentium 4 and that was my first PC that I actually fully built myself lol) - I imagine it would help with temps, but if your temps are already fine (which they are) it isn't really necessary.

Most motherboards in the last 7+ generations have the ability in BIOS to control fans based on CPU temp, so plugging the second fan in to a different header is not really an issue.

You'd definitely want to do 1 fan as intake and the other as exhaust, even if the fin stack is open on the side, you'd be creating turbulence having both fans blow in & it would probably make temperatures worse because some hot air would probably be stuck in the middle for a while before whirling out.
