Having some issues with my 240. Bouht it last year and it has relatively low hours on the rig maybe 150 to 200 hours. I'm starting to have intermittent problems with the pump at least I think it's the pump.
Basically I'll power up the computer and within a minutes fans spin up to high and temps rise, near as I can tell the pump is not powering on. I have watched ir in the bios and on AIDA64 and where ever I plug in the pump I get random 0rpm readings on that sensor. Tried new bios and motherboard drivers. Tried different monitoring software and no software'
Seems the only fix is to usually power off and the start rig again. Rarely will a restart fix the issue. When the pump is working my cooling is awesome.
I'm wondering if this issue has been a problem in the past. Hard to believe this pump is flakey.
