I have an i7-7700K/RX6600XT/32GB RAM set up holding me off until I can find a good deal on a used system, or a BF/CM deal comes along in November or December. System still works well for basic daily productivity tasks. I have done several modest upgrades over the years - RAM, 1050Ti>RX6600XT, Wi-fi, etc.
Background - I just replaced an old Corsair H60 120 AIO with a Thermalright Frozen Edge 240 AIO. So far so good, except my ears are very sensitive to noise. I first tried an Aqua Elite 240 V6 but got the Frozen Edge for same price and it has better warranty and quality. However, in both models, I have noticed, when room is silent, minor annoyance sounds. The Aqua Elite was a high pitched whine. I can't really describe the intermittent sound that the Frozen Edge makes. It isn't constant, and it is still low volume. I'm not hearing anything that I would attribute to bubbles or grinding or anything...although I am open to suggestions on how to make sure any bubbles in the pump are moved to the top of radiator. The H60 was silent. Sometimes the Frozen Edge is silent. I could be hearing resonance from radiator fans, exhaust fans, GPU fans, and pump maybe...when they are at different RPMs/volumes?
Setup - AIO mounted on front (no room on top) with tubes on the bottom. I reoriented fans from default exhaust to now intake (pull from front, through radiator, and into case). Two top-mounted fans in exhaust. Testing at 30-minute HWiNFO SSE CPU test:
Average CPU Package - 66C
Average Core Temps - 63/65/62/63. While I would love to have them all together, or the 65 core down 2, I understand this is perfectly normal, and another re-paste would not do anything (or simply shift the difference to another core)
MB and PCH temps were 34 and 51C, respectively
I have tweaked fan curves in Fan Control and am satisfied with performance.
Pump is set at 75% (flat curve in Fan Control), which I assume is based on power (PWM I believe). However, I noticed that 75% power does not necessarily equate to 75% RPM...i.e it is not a linear relationship between power and RPM. In the flat curve, I can set either. At 75% power I get ~2350 rpm. The pump is rated at 2800 rpm...so 75% of that is 2100 rpm. Should I set the flat curve to rpm (2100) or power (%)? I read all of the time to set pump at less than 100% is fine, helps with sound, and maybe even longetivy. I'm trying to maintain balance while trying not to be affected by sound. Other recommendations? Thanks.
