I have a i5 4670k with h100i cooler, when running prime 95 with cpu stock speeds (3.4ghz) temp exceed 70 degrees

Pls help i really don' t know what to do, I have read through forums and tried various things like remounting the cooler and changing the thermal paste also changing my fans around for optimal airflow but nothing seems to make a difference.

  1. If that's the best the AIO cooler can do at stock, I'd send it back and go with a $35 212 EVO. I presume you have a roomy case w/good airflow and the rad/fans are mounted as per the manufacturer's advice.
  2. Its not the cooler itself as i recently upgraded from a h75, this is what i though the problem was. I have a corsair 600t btw.
  3. Btw, here is an easy to follow guide for the H100i if you want to verify all was done correctly: http://www.corsair.com/en-us/blog/2013/february/how-to-install-the-hydro-series-h100i-cpu-cooler
  4. I was told that I could have a "bad chip". May this have some relevance ?

    Oh! In that case, I think I would temporarily remove the pump from the CPU and disconnect its wiring. Then install the stock cooler and run the same prime95 test. See what the temps are with the stock cooler so we have a comparison.

    Are you using the Corsair Link software to modify anything?
  6. i also have a sabretooth z97 mark one, i heard something about cooler not making full contact with the cpu ?
  7. Hi Luke, I'm getting an Asus board also for an i5-4690k and one of the things I heard in my travels when talking of coolers is that some chips are running hot on Asus boards because of the default voltage they have set for Intel chips in the bios.

    You may want to report here what your voltage is on idle and on Turbo boost so we can compare it.

    Others have decreased (safely) the idle voltage and gone from there.

    Here's a link on the issue.

  8. Well, all these are possibilities. But as far as the contact surface, you said you mounted it correctly. I know from my experience with my H60, it can be a bit tricky to hold the pump flat to the CPU as you add/tighten nuts to the magnetic mounting frame.

    But my little H60 cooler will only let my i5-4690k up to mid 50s at stock. So the H100i should be at least that good if not better. That's why I was curious what kind of temps you got with the stock cooler.

    What version of prime95? For haswell, it should be the older version 26.6 with small fft's. The latest versions push haswell harder than necessary and tend to give extremely high temps.

    Hey, that's good to know. That may explain why my temps were unusually high above 4.2 GHz. I thought it was just the limitation of the little H60 AIO cooler. It passed Intel Burn Test at 4.6GHz no prob. But p95 took it into the stratosphere.

    Yea i was gonna get the z97 sabertooth mark 1 but now em gonna upgrade my gpu. Anyways, while i was researching i found out that the sabertooth mark 1 is not compatible with the h100 if i remembered correctly. It is because of the voltage regulators or something else that is located just above the cpu slot so if u were to install the h100 it won't fit properly. Did u notice any fitting misplacement? like is anything tilted? im an air cool kinda guy so it didn't bother me.
