is this overkill?

Case Fans - How many should you have?

With the top exhaust fans ON, the hot air is quickly pushed out of the system, giving the GPU cooler to breath instead of the hot air circulating in the system.

So, conclusion. No, it is not overkilling to put that many fans. Haha.

if fractal define s, partly cud be the rear venting is small, so turning on the top exhaust fans really helps...

You could be right in that. If unsure, just add more Fans!

at least increase rear fan rpm, is it only at 800-900+ rpm?
i imagine ur ftw 3 large gpu fans is taking in air at a higher cfm than the rear fan is exhausting air...

It's possible that using AIO coolers affects VRM cooling in terms of airflow moving past the modules itself.

I was initially eyeing Gigabyte Z370 Ultra gaming, until I saw a post(here) followed by a vid(utube) on how VRM were hitting 100C. With some googling, I found similar complaints and initally concluded that gigabyte suck balls (Sorry gigabyte fanbois).

But when I revisited this topic, I noticed everyone using AIO coolers had this issue, leading me to question my existance for dissing Gigabyte....No I mean my conclusion. So maybe there's some drawback with AIOs?

HSF: heat sink fan aka the fan mounted to ur cpu

ok ah... here's my micro atx case:

this looks...hot
might as well go back to front if lack space
bottom front oso can

The rare fan is 1000 rpm. However, it does push a lot of air due to being 140mm. Any faster, the fans will get loud. I prefer the silence! I agree the GPU is pushing a lot of air through its heatsink.. that is why it'll be good to have top 2 fans as exhaust..

Yes. AIO don't have air blowing over the VRMs like a normal Heatsink/Fan thus Cryorig made an AIO with an additional fan for the VRMs!

yeah i guess its ideal for ur aio placement & setup then, not front to back for ur casing & aio
i forgot stock fans are around 1000 rpm. my stock corsair fans do almost nothing at 800-900, and at max just very gentle breeze - put hand behind fan feel almost no force unlike the air gushing out of my gpu...

quick qn.

does room temp make a big diff in the CPU temp?

reason i'm asking is tht i swopped my CPU cooler fan from intake to exhaust and saw a drop of 3 degrees when testing peak but i'm not sure is this because of the rainy day too

 

[tangpx]

Yes, slight difference.

Yes, slight difference.

so can i say tht the 3 degrees drop is partly because of the direction switch of the CPU cooler fan?

 

[tangpx]

If the front casing is air intake, the cpu cooler should follow the same direction. The rear case should be exhaust. This is a one way direction.

The other is depending on the room temp. If you use air con, the temp will drop further more.
