Looking for a Air CPU cooler.

[Smiffy-UK]

Hi, if I'm honest I feel I'm having heating problems with my rig, my Current CPU cooler seems fine for the cpu. But I've just purchased 2x Phanteks PH-F140MP PWM 140mm Fan (for intake) and 3x Phanteks PH-F120MP PWM 120mm Fan (exhaust 1x rear 2x top) about to install them today.

My rx 5700xt gets very hot under heavy load. Reaching 93deg after just 30 mins of gaming.

Now I'm looking for a new CPU cooler to help with the air flow in my mATX kolink citadel case CA-03K-KK.

That being said, I have the b450 mortar max mobo and 4x8gb sticks of Team Group Xtreem "8Pack Edition"

My case states that I can have a cooler with a max height of 160 mm.

My thoughts were to set it to pull the air from the gpu (bottom of case) to push the air to the two top exhausts. Hopefully helping my heating problem.

High graphics card temperature means need for more case cooling.
CPU cooler can't do anything to that.

Front intake of that case is bad marketing design and restricted.
With little space behind that mask you should attach front fans to inside of case frame to give them some more space to draw air in and make their job that little bit easier.
Also that BS fad shroud is another cooling obstacle basically making lowermost front fan position useless.
Though if leaving that empty block that one hole with some cardboard to prevent fans from recirculating same air.

With front intake not that great in any case could try using top to also force in some more fresh air and remove all expansion slot covers.

For CPU Arctic Freezer 34 would be good for budget

Sorry to tell you, but using top vents, especially in front half of top will pull the cool air front intakes are pushing into case up and out of case before reaching CPU cooler .. and at same time pull heated exhaust coming off of GPU up where it will go into CPU cooler raising CPU temps. I've found 99% of the time cases only need good front intakes with all openings in front fan mounting panel not covered by fans blocked off so air can't leak back in front of fans, but has to move on through case and out. Remove all PCIe back slot covers/vents to increase rear vent area around and below GPU and thus improve front to back airflow. Link below is to basic guide to setting up case airflow:

Thank you both for the replies,
so what I have done is fix 2 intake 140mm fans (I could only mount 1 on the inside and 1 bottom front) and 1 exhaust @ 120mm rear, I had yesterday taken all the vents off then realised I could also take out the GPU clamp? Whatever the holder clamp this is called it's gone and now more vent's outback of the case, erm so job done I managed to get -10 degrees from GPU with a 30 min stress test 84.C max -7 from CPU and the glass side doesn't even reach room temp also, not even any louder so case closed i guess there's a pun there somewhere.

Result.
The main issue now is most of the GPU now will blow hot air to its sides, over the M.2 and against the side panel.
Not a problem with the Asus HD7970 DirectCUII I was using before. Ideally if the GPU would blow 99% of the air out, the temperature inside the cases would be much better.
As mentioned before, had issues with a Vega 56 which during game was causing the M.2 to throttle.

Tbh why not save on a better cpu cooler, a great one like a Noctua NH-D15/S will set you back £70-89 and buy a case known for great cpu & graphic thermals? Gamers Nexus review cases and their cooling ability. This, above all else will have a huge factor were your cooling is concerned.

My quick recommendation is the Cooler Master H500. Front mesh case with 2 200mm and a 120 mm rear fan preinstalled. Chart topping gpu cooling on Gamers Nexus. Great review across the board, have a watch on Youtube. I own it and love it with plenty of cable management behind side panel. It has an RGB controller but I added a fan controller as well to ramp fans up to 100% on the fly for my overclocking.
