Hi All,
Just wanted to see if anyone else has noticed the same thing over the years. I've had two Corsair AIO cooling units. The H100i and the H115i.
In both cases, I've noticed that a year or two after initial install temperatures aren't as good as they were initially. Just FYI, ambient temperature is cooler today (while I investigate this) than it was when these systems were originally set up. We're having a bit of a cool day today. =)
---------------------------------------------------------
Corsair H100i
On the H100i and my 4770K, at initial install and OC (to 4.5GHz), temps were 81c / 79c / 87c /81c for each core. Under load in Prime95 w/ 512k min FFT
Three years later, I note that temps are at 98c / 93c / 97c / 87c
I wash the radiator to clear some dust build-up that compressed air couldn't remove and remount the block. . . 86c / 89c / 89c / 85c
-----------------------------------------------------------
Corsair H115i
Initial install was a year ago with a 6700K at 4.6GHz. Temps were 76c / 80c / 68c / 74c
A year later, I noted today: 89c / 90c / 86c / 87c
After some dust blowing and a remount of the block, I was able to get this down to: 81c / 82c / 75c / 79c
Those are respectable. But nowhere near what I originally got with the H115i.
-----------------------------------------------------------
Does anyone see this gradual degradation of AIO performance over time. There doesn't seem to be much else for me to do to try to rejuvenate these coolers and get them back to where they were when new.
Is this due to the AIO units aging? The CPUs aging? I tried to rule out changes in the testing environment by using older editions of Windows 10 (1607), Prime95, and HWMonitor.
