I was getting high 80s - low 90s when gaming with the stock cooler so I upgraded to a Noctua U9S but am only seeing a decrease of about 10 degrees when gaming. Light use like browsing chrome has it at high 40s - low 50s.

My case is the Fara R1 Pro with the case fans that come with it and a B550 tomahawk motherboard.

I've tried reinstalling the cooler with fresh thermal paste and also turning off PBO in the BIOS with similar results.

I assume you refer to Noctua's included "Ultra Low Noise Adapter". That can easily be detached. It's optional.

It makes a very quiet cooler fan even quieter. You don't need it at all. I've never used mine.

It likely prevents the fan from turning above a very low RPM. You don't want that.

After you get rid of it, use a tool like HWInfo64 to see exactly what speed your case and cooler fans are spinning at.

Your PC BIOS likely has a mechanism to control fan speeds. You can likely force them all to spin at or near their maximum rpm. Look in the BIOS.

I have all of my fans set for "silent" mode. The U9S fan spins near a constant 800 and the 2 Noctua case fans spin near a constant 500. I don't use a video card and care more about noise than temps....which are very low anyway.

Set all fans to run as fast as possible and then re-evaluate temps and noise levels.

I have a U9S but I don't game.

It is an excellent cooler for its size, but it is short and would typically be used only with a fairly narrow case that could not accept a Noctua U12S or U14S. It has a 92 mm fan rather than 120 mm or 140 mm.

I assume you cannot use a taller cooler? The U12S (which I have used) should give you roughly 5 degrees lower temps if your case will accommodate it.

What are your ambient temperatures? Right now, my i5-6600K CPU is idling at 27 degrees (81 degrees Fahrenheit) on a U9S in a 22 degree ambient room (71 degrees Fahrenheit).

You could try dual fans on the U9S, but that likely would not improve temps by more than a degree or two.

Is your Noctua cooler fan running at max speed?

My case might be able to support more but I've already put the cooler to use so the place I bought it from won't take it back for a refund.

I'm not sure of the ambient temps but at night when it's cooler the temps drop by about 5 degrees.

I don't have enough clearance next to the ram to fit a second fan.

Not sure, how do I adjust the fan speed? I do have the silent fan cable attached.
