Overclocking 2500k and temperature questions

I completed my first pc build last week. I went with the i5 2500k and the hyper 212+ fan and heatsink. Putting thermal paste on was my biggest concern and it looks like i did it right. Idle temps for the cpu using hwmonitor are in the mid 20s and after some good gaming sessions, they temps are in the mid to upper 30s. Highest any of the cores have ever been is 41 degrees.

I'd like to overclock the cpu to 4.3 or 4.5 ghz. What kind of temperatures should i expect by doing that? I've never done this before so I assume if your cpu cant handle a certain oc, it will shut down to protect itself, correct? If that happens, I should lower the clock speed to something that is stable. Any tips would help.

  1. Those cpus can run up to 70c (officially 73c according to an Intel rep). If you want a stable overclock, drop the ram speed to 1066 or 1333 first in manual mode before increasing the cpu fsb.
  2. http://www.tomshardware.com/forum/265056-29-2600k-2500k-overclocking-guide

    BTW, my idle temp is 44C with 2500K and CM Hyper 212+. Ambient temp, 24C.
  3. High 60s to low 70s with that heatsink and OC.
  4. The tcase for the Intel® Core™ i5-2500K is 72.6c this is really the temperature that want to aim not to go over. On my Intel Core i7-2600K I am at 31 idle with Cooler Master hyper 212 + and havent gone over mid 50s with under load with it. http://ark.intel.com/products/52210/Intel-Core-i5-2500K-Processor-(6M-Cache-3_30-GHz)
