[SOLVED] Ryzen 7 3700x AIO temps high

[jlcpremier]

Recently upgraded a media server from an i5-9400 to a Ryzen 7 3700x. Idle it sits around 40-45 degrees, but when CPU encoding with Handbrake it's gone as high as 86, but on average is between 78-84. I had a Corsair Hydro 55 AIO that I retained to use for this setup that's about 4 years old now, so I'm wondering if it's time to replace it or do those numbers sound about right? If I did need to replace it, would another 120mm work or should I look at a 240mm AIO? Thanks

Full specs of the set up...

CoolerMaster N400 case
Ryzen 7 3700x
ASRock B450M Pro R2.0
8GB 2666 DDR4
Corsair Hydro 55 AIO 120mm mounted at rear of case as intake
2 SSD
5 NAS drives
5 CoolerMaster SickleFlow 120 ARGB fans
- 2 front intake, 1 top exhaust, 1 side exhaust, 1 intake attached to AIO radiator in rear

Those numbers don't seem terrible to me, based on what we know about how the 3000 and 5000 series CPUs behave, but it's also equally likely that a 4 year old AIO is experiencing age related problems such as growth related restrictions in the tubes, radiator or pump, wear in the pump that has reduced pumping capability or permeation (Air in the loop from coolant loss through the hoses or micro leaks at fittings).

I'd probably look at a new unit, these are really only good for around 4-5 years in most cases and I'd definitely look at a 240 or 280mm model for that CPU depending on what your case can support.

Since we know that these parts will maintain their boost behaviors for longer periods of time with better cooling, it kind of makes sense on multiple levels.

Not terrible or unexpected temps for a 120mm cooler. Just because it's "water" cooler it doesn't mean it's better than a decent air cooler of same (fan) size.
Don't know how you set up 3700x, if boost and PBO are enabled or at which voltages it's running but in my experience even a 240 AIO is too little for getting most performance out of 3700x specially in summertime. It needs to stay under 70c for that. For every 2c over 70c it looses about 100-200MHz in boost speed.
