i5 3570k Extreme high temps

Hi everybody,

I recently purchased an i5 3570k and had no issues installing it to upgrade from my i7 2600k.
Long story short, I wanted pci-e 3.0 support so I went with the ivy bridge. Now on to my problem.

I have a Corsair H60 cooler because I don't really do any cpu heavy computing, just gaming.
So naturally when I got my rig up and running with the new i5 I wanted to test the performance and cooling and all that jazz. To my enjoyment at idle the budget H60 keeps the 3570k at 18-20c but when I start prime 95 it IMMEDIATLY jumps to 70c and rapidly (with in 30 seconds to a minute) climbs to almost 100c before I can stop the prime95 tests!!!

On the other hand it hovers around 75-80 when gaming.
I understand that that's not all that hot but it shouldn't be that high for either scenario under a water cooler right?

I have reseated the cooler twice and it is oc'd to 4.2gz. but 100c!!?? come on.....I had the 2600k up to 4.5 and it never got over 75c with prime after hours of testing.

  1. Put your ear up to the pump/waterblock while stress testing. If you can't hear a buzzing sound it means your pump is broken.
  2. Thermal Grease.

    How did you apply it and did you remove the old stuff? Also is your cooler seated evenly on your CPU. How did you tighten the screws, in a star pattern?
  3. I put new thermal grease on after cleaning the block off in the center of the cpu about the size of a fat sesame seed and I pressed the block down on the cpu and tightened the screws in a star pattern. BTW this is not my first build, I do this as a side business/hobby but I am unfamiliar with ivy bridge cpu's as this is my first.

    Sorry. You never know.

    I would than go with the first poster about the Pump or the Power to the pump. Hook up a volt meter to the inputs of the pump and see what you get. It could be a bad solder joint.

    That sounds like far too much paste to be honest.

    Sounds obvious, but double check both the pump and the fan on the radiator are powered.
  6. You know what? Go to an online retailer or a computer store, and buy a Cooler Master Hyper 212 EVO, just for the sake of testing. If it keeps the temps low, then keep it, because it's cheaper than a new water cooling system. If it doesn't, it could be an issue with the CPU itself, or your OC.
  7. Luckily this cooler has a 5 year manufacture parts and labor warranty, but when I get home this evening I will check the pump on it.

    Also, if I get an air cooler in place of my H60 I want this one,

  8. The pump is running fine. I started the pc with the pump unplugged and the temps idled around 40c. Apparently this cpu gets really hot really fast under oc. I have read in other forums that a slight or even no change in voltage when overclocking causes the heat issue. Most people with this chip do overclock the frequency but under clock the voltage!!

    "no change in voltage when overclocking causes the heat issue"

    Yes, but you have change the voltages to get your system stable. If you have your voltage too low for your over clock your system will crash do to instability.

    That said, if you are able to run Prime 95 at your stock voltages then stay with it. You must have one of those golden over clocker CPUs. I have never been so lucky.

    As for your issue I still think it is your thermal paste but it could be a bad cooler. Like suggested above, if you have an air cooler around hook it up and see what you get to rule out if the problem is the cooler.

    The other thing is how old is your paste? Did it come out of the tube dry and clumpy looking?
  10. My thermal compound is more than 6months old but it's in a tub. It's more like grease and not dry at all. The only air cooler I have is the stock one, I can try it tonight just to get another reference. I'll try to do it early and post back here right after instead of making you guys wait another day.
