Cooling advice please, fans to intake or exaust?

[scopio]

Hello guys,

I will be building a rig with the following components;

Case-Corsair Obsidian 750 Full Tower ATX
Motherboard-Asus ROG STRIX AMD Ryzen X470-F GAMING AM4 ATX
CPU-AMD AMD Ryzen 7 2700X Gen2 8 Core AM4
Memory-Corsair Vengeance RGB PRO Black 16GB 3200 MHz DDR4
PSU-Corsair HX850i 850W Full Modular
GPU-AMD Radeon RX 590 Red Devil 8GB GDDR5
Liquid cooler-Corsair Hydro H150i PRO RGB
SSD-Samsung (MZ-V6E500BW) 500GB 960 EVO PCI Express 3.0 x4 NVMe
HDD- Seagate 1TB 3.5" SATA 3 Hard Disk Drive/HDD ST1000DM010
Optical Drive-ASUS x24 DVD/CD Re-Writer with M-DISC Support
Wi-Fi PCI-E Card-ASUS PCE-AC88 AC3100 Dual-Band Wi-Fi PCIe Adapter
Microsoft-windows-10-home-Retail

I require expert advice on whether to have the fans to draw air in or to push air out when fitting the AIO Corsair Hydro H150i PRO RGB at the top of the Corsair Obsidian 750 Full Tower ATX case as it will not fit at the front where there are two 140mm intake fans. It also has one 140mm exhaust fan at the back.

Since I don’t intend in replacing any of the components already bought and will not be OC my dilemma now is whether to fit the fans on the Corsair Hydro H150i PRO RGB above the radiator or below the radiator or as intakes or exhaust?

Hi

Try experimenting and see which gives you the best temps. Most folk have top fans exhausting but there is no set rule.

The fans can be placed under the radiator in both intake or exhaust. It is just a matter of flipping the fan around. There should be a small arrow on the fan frame that indicates airflow direction. So it will either be pulling air through the radiator into the case, or pushing air through the radiator and out through the top.

Thanks Lee for your input.

normally push out of the top.
(and not for the reason that hot air rises - lol)

negative pressure , normally best tempts but draws in DUST from EVERY unfiltered hole!

positive pressure is normally used as just only enters via intake fans which means cleaning out the filters but little dust inside the case
