How easy is it to "fix" a clogged corsair AIO (H100i GTX)

    Seems that my H100i GTX has a clog in it. It's no longer giving me decent cooling (CPU overheat in <30 seconds with anything that actually uses all 6 cores), and testing shows that the temperature of one of the hoses stays exactly the same idle vs load while the temperature of the other hose climbs almost 10C and rather quickly (measuring the outside of the hoses using an IR temperature gun). Corsair support says the radiator can only remove 1-2C in one pass so there should not be a huge temperature difference between the hoses, and that this problem is a "known issue" with this model.

    So I assume it would be a matter of taking it apart, draining it, cleaning it, putting in new liquid, or similar. I'm just curious if anyone here has actually done this with a clogged Corsair AIO, as I've heard they are not particularly easy to disassemble (because they aren't meant to be taken apart by the end-user). Is it generally even worth the effort to try and salvage?

    Usually when this happens its a sign of a dead pump.
    Its possible to splice in a new pump to reuse the aio but its not done very often due to cost. Most quality pump/res combos cost as much as or more than a new aio. If you decide to reuse the aio there are guides as to how most pump heads come apart.

    Are you monitoring pump RPM? (you can do this) I'd check that before endeavoring to disassemble it.

    pretty easy. ive done two, a h60 and a h75, same shit but one is round one is square. cut the old hose off, cleaned the rad and pump, re-hosed and refilled with af/water mix. both still working and both are 6-8 years old. both had clogged hose barbs, the h75 had clogs in the cold fins too.

    The pump still reports ~3060rpm in Performance mode and ~1900rpm in Quiet mode, which is consistent with what it has always reported. The small amount of cooling that the AIO is still able to provide, despite the clog, also does still vary between Performance and Quiet mode. Those things lead me to believe that the pump is still working.
