80C CPU on Idle - H60 Not Working? Please help. Is it broken? Should I get a new Cooler?

Apologies, this topic has changed a bit and should be in another forum.. originally had trouble getting into my ASRock BIOS in addition to the below issue.. but I handled that much, at least.


Hiya - earlier tonight, was using my setup in HTPC mode and it shut down.. I'm assuming it overheated, because I opened my A-Tuning (ASRock tweaking software) on reboot and saw my CPU temperature running around 80C at idle, up to 95C (!).

Which is, clearly, not good.

I have push/pull fan setup, CS450M inverted to extract air, running a simple i5-4590 with EVGA GTX 750 Ti Superclocked in a Cooler Master Elite 130. Nothing earth-shattering.

Also have a Corsair H60 (supposedly) on CPU cooling duty. The push fan is attached to the CPU fan and the H60 is hooked into the 3-pin case fan.

Now, I've been playing The Witcher maxed out for a couple weeks and had no issues until today.. admittedly, I was not monitoring temperatures, but I would assume The Witcher runs hotter than an episode of Longmire running on XBMC.

I have already removed the H60, cleaned it off and reapplied thermal paste, in the event the thermal paste/mounting was to blame. No change. While I've never mounted a liquid cooler before, I'm pretty sure it's mounted correctly. Not too much paste, either.

Got into my BIOS.. the fans were all listed at default setting. I cranked them, just to see.. no real difference.

I am presently at a loss. I'm tempted to throw the stock cooler back on the i5-4590, to see if that brings the CPU temp to something a bit more reasonable (for reference, MB temperature is 26C, roughly 1C over ambient temp). I'm also open to recommendations on what might fit into a Cooler Master Elite 130 and provide good airflow, if the H60 is just DOA from Overstock.

Thanks in advance for any help.. any help at all.

    well, feel the two tubes of the H60 - one should be running pretty hot if the CPU temp is at 80C.

    Also listen carefully if you can hear the pump of the H60 running.
  2. Heya - tubes on the H60 weren't doing squat.. I'm doubtful the pump was working at all.

    Picked up a Thermaltake 3.0 Performer late yesterday, installed it and my idle is running between 29-31C.. along with some Noctua fans (instead of the stock Thermaltakes), she's running cool and quiet.
