who here mixes / matches fans in their cases?

to me it seems unwise, unless your exhaust fans are better than the intake so there's some negative pressure in the case.

can get craxy expensive to fill all the fan spots though. my Phanteks XT Pro Ultra has space for another 6 fans and the fans it comes with can be purchased in 3 packs for $80.00. >.<
 
I use "flow" fans in the front and "pressure" fans in the back/top.

NOTE: Single fan on top closer to the rear (behind CPU Heatsink) not to deprive CPU fans from any air, only take air out that has passed through the heatsink already.

My intake is flow, I need more flow to spread around components.
My outtake is pressure, I have to force air out and make sure it gets out.

interesting. I would have thought high CFM for intake / exhaust being pressure fans were built specifically for use on HSF and radiators. 🤔

I don't currently have mismatched fans (interesting idea though) but I definitely second the comment about the single top fan closer to the rear. @Bond007 put me on to that option originally and it improved my CPU temps.

Nice to see others recommending it too. More fans is not always the best answer!
 
All the radiators have NF-F12 fans for the high pressure performance even at low RPM. The generic case fans were whatever super cheap RGB fans I could find with low stall speeds for general airflow. Radiators are external so visually right now you don't see the NF-F12s at all.
 
I wouldn't do it due to aesthetics in the first place. All my case fans are eloops atm. My external rad has Noctua but you can't even see them.

I am big on airflow and I love these discussions :)

So yes, it can also depend on your front-cover of your case. For example, not all cases are created equal and some cases have horrible airflow channels (non-mesh and even mesh with low density (space between holes and the size of the holes), but we'll get into that later):


So let's get nerdy and break this down:
-- Proper mesh case:
--- > Front: Flow-type fans (120mm or 140mm)
--- > Rear: Pressure-type fans
--- > Top (single): Pressure-type fans
--- > CPU Heatsink: Pressure-type fan(s)

-- Mesh case with poor density or Case with poor front airflow channels:
--- > Front: Pressure-type fans
--- > Rear: Pressure-type fans
--- > Top (single): Pressure-type fans
--- > CPU Heatsink: Pressure-type fan(s)

For pressure fans I recommend:
Thermalright TL-B12

NOTE: These are POWERFUL fans, you need to control the fan curve, but holy smokes they rock! I test them in case airflows and radiator cooling, INSANE!
 
Pretty big into airflow myself, but don't have the time this second for a big write-up.

Sufficed to say, it always depends on the case, what's in it, and where it is. There are no 100% universal rules for airflow really. 🤷‍♂️

I have no problem mixing fans. I am also not afraid to use more than one hub :)

In my current setup I am using the stock 2x 200x38 intakes, and the 140x38 exhaust. I am also using 3x Thermalright TL-B14 as intake at the top, and I have 2x T30s on my CPU cooler. Its better than my Torrent Compact.

I own a Metro Datavac ED500, so I am running a filter free lifestyle. Because like condoms, they just get in the way.
