Additional CPU cooling

[fire_munki]

I've got an AMD Ryzen 7 3700X with a Cooler Master MasterLiquid Lite 120 and the CPU fan will spool up and down like a sine wave.

I was thinking of adding an extra 120mm fan to the other side of the radiator so that they would both spin a low rpm instead of one spooling up to 1600rpm when gaming. Is this a valid idea or would the extra fan not increase the cool effect much?

The fan noise is pretty noticeable so a reduction would be good.

It might help a few degrees - not by miles. The issue isn't really the specific temperature, it's the fan curve that's configured for the CPU.

I think you can improve it using the Ryzen power plan in Windows, try searching these forums for it. Fans ramping up and down is a common complaint with Ryzen.

That is a fairly small CPU cooler for your CPU but you can help it along - make sure your case airflow is good. Making the radiator an intake (fans blowing air into the case) will also help.

Tells lot about that waterhype cooler's abilities/lack of them that it can't even moderate short temperature spikes...
Assuming BIOS has fan curve adjustments try to adjust them, or change control profile to other.
