The heatsink in my desktop computer. Ugh. First the fan makes a rattling sound, then I manage to destroy the fan while trying to disassemble it to grease it, then I replace the fan with another 120mm fan I had to see if it would fix the issue, but I eventually discover that this fan doesn't push enough air by itself to keep my machine cool, so I try installing another fan alongside it, and while I'm at it, I manage to strip the hole on one of the bolts that the retention clip mechanism screws into.
I fought with this heatsink for several hours trying to reinstall it, but it was just being an SOB the whole time, and I managed to make enough noise that I'm pretty sure I've woken up my roommate, which is quite a feat given he's an older man who is hard of hearing and takes sleeping pills. He hasn't complained, but I feel really bad of rhim, and now I'm worried that this is going to provoke a negative reaction tomorrow. Thankfully, I had my old heatsink and fan set aside, but I dropped $40 on this stupid thing, and in the process learned NOT to trust online reviews. Cooler Master SUCKS. Their cases suck, their heatsinks suck, their fans suck, they just flat out suck! The next time I buy a heatsink, it's going to be from a brand like Noctua or something. Hell, even Rosewill, Newegg's store brand, makes better stuff than Cooler Master.
My god, I wish I had some place to go where I could just scream my head off and smash things. Do neurotypicals even realize how painful it is to have to internalize your meltdowns? I think not.
