[SOLVED] Cooler suggestion for i3 8100

[sagor1]

Hi everyone, currently i am using Antec h600 pro aio cooler.I brought this 2nd hand.I am not sure whether aio is faulty or i didn't setup it perfectly.
On idel my cpu temps around 43-47 during gaming (the crew 2) it's 67-75 or more.Which is only 50-60% cpu usages. And the temperature is close to intel stock cooler.
I live in Bangladesh & it's hot outside 32-36° (humidity is more).I don't know my room temperature😐.
If it's a faulty then please suggest me a cooler below 50$.
Spec:
I3 8100
Asrock B365m phantom gaming 4
SAPPHIRE Pulse Radeon RX 570 4gb
Antec DP501

Note:I plug the radiator fans infront of the case,below one.And two other fans are exhaust fan 1 comes with this case & the other comes with the Antec DA601.
I did't tight the pump screw too much, it's already feel too tight. Should i lose it a little bit?
The radiator i attach upside down because of the pipe.Also many of the radiator fins are mashed from both side, but there is a gap.

The pump/waterblock screws should be tight but more importantly evenly tightened so that it meets the CPU right. I'd run two fans on your radiator in a push pull configuration and just give the radiator a good dusting, and replace the thermal paste with a quality one like Arctic MX4/Arctic Silver 5
