Question CPU/Computer Getting Fan

[DylanHickeyy]

I have recently upgraded to an AMD Ryzen 7 5800XD from a Ryzen 5 5600.

At the same time, I upgraded from an Uphere 6-pipe CPU cooler to a Thermalright Peerless Assassin 120 SE CPU air cooler. My PC is emitting a lot of heat, and the CPU is running at an average of 75-80°C under 80% stress and 90°C at 100%.

Have I set the fans correctly? I have 5 fans: 2 exhaust at the top, 1 intake at the back, and 2 at the front. I have the two CPU fans blowing air over the CPU through the heatsink to direct the heat upwards.

Here are photos of my CPU fan and a rough sketch of my PC configuration:

The fans on the cooler and the rear of the case are in reverse, you should set them to push air through the cooler towards the rear and the rear fan in the case should be set to exhaust.

So like that? Now have 3 exhaust and two intake?

Yes.

In general, front, side, and bottom fans are intake. Top and rear are exhaust.

All about air flow through the system.

Got ya. I'll change them around tonight to suit. Thank you.

Just curious would 2 fans be enough and does having more exhaust fans than intake put it under a large amount of negative pressure?

Ignore the negative/positive thing. It really matters very little. The flow will stabilize once in use and you'll be fine.

Personally I prefer more intake than exhaust to create slight positive internal pressure. But that is almost entirely to reduce DUST influx. It is NOT essential.

IF you change as advised and still find temps a bit high, you could consider adding a third front intake fan if there's space for it.
