Hi all,
I've been having tons of issues with my HP Obelisk Desktop PC - 875-1040st CTO over the last few years and finally have to replace the CPU cooler. It appears to be a closed-loop liquid cooler of some kind and I cannot for the life of me figure out exactly what it is. I wanted to just buy the exact same one as to not have to rip out the mobo and mess with the back bracket but I'm having trouble figuring out what even this cooler is. Any help would be appreciated.
