Can I overclock my i5-2500k to 4.0GHz using stock cooling?

Just a quick question can I overclock my i5-2500k to 4.0GHz using stock cooling? Would it be stable, would I have to change the voltages and what not?

More about overclock 2500k 0ghz stock cooling
  1. I would use an aftermarket cooler....$25 for a Hyper 212 will do 4.0 - 4.4 Ghz.

    $50 Scythe Mugen 3 for 4.5 - 4.6

    $80 Thermalright Silver Arrow for 4.8 - 5.0
  2. The stock cooler is meant to be run at stock speeds. Overclocking tends to require after market cooling. I can vouch for the Hyper 212 because I use it in my current machine and it hasn't had any problems since I bought it several months ago.

    I agree with the above post on what coolers for what clock rate although I'm not sure a 2500k would have a long life clocked around 5GHz regardless of the cooling unless you get a ridiculously lucky chip.
  3. what motherboard are you using? I own an Asus motherboard and it can Autotune to 4.3ghz on stock Intel cooling. Asus tested their autotuning to make sure it would work with stock air cooling, you should be able to hit 4.0ghz easily using about 1.3 volts or so.
  4. even a hyper tx3 will do 4ghz quite easily if you dont want to pay the extra or dont have room for the hyper 212+.

    It's a GA Z68XP UD3P. It has a touch BIOS which seems to make things more simple, but I don't mind using the old BIOS. My stock cooler idles at around 27-29C which is really good, and was just wondering if I could get away with it.

    I think NH D14 should go on there ;)

    Of course yes. But since you got the i5k and the UD3P, why don't you go for some better cooler. You won't regret it. I also have the same board and the i5k. Just done OC it to 4.0ghz with vcore @1.212v. Max load is well under 60C with P95. I'm happy now cause finally I got to my goal even though I'd wasted some money on other board and cooler.

    If you have a mid tower case like mine, you should get a small HSF like 92m. Beside you wouldn't want the big heavy thing putting stress on your board.
  8. i own an Asus motherboard and it can Autotune to 4.3ghz on stock Intel cooling.
  9. i got the 2500k with a cm 212+ @ 4ghz with v-core of 1.2 with max temps of 46C in prime although its not hard to hit 4ghz with this chip deffo recommend aftermarket cooling
  10. Yep no problem to 4.0GHz with stock cooler!
  11. I use to have a stock heatsink, and despite good airflow, my rig crashed to bios twice at stock speeds during CPU intensive sessions. In retrospect, I probably should have underclocked.

    That is why I went and got the Cooler Master Hyper 212+. I can overclock up to 4.5GHz (with proper airflow) using this.

    Overclocking your Sandy Bridge, upping the voltage, or anything like that without an aftermarket cooler is asking for trouble.

    If it was an AMD CPU, I would say go for it (what would you have to lose?). But as it is, you have a lot to lose.

    I'm definitely going to get a aftermarket cooler now. I was thinking a Corsair H60, but am also looking at the 212+. I want to OC to 4.5GHz, my only problem is finding an overclock guide that uses a Z68 Gigabyte board. Did you notice a significant difference going up to 4.5GHz?

    I have the 212+ and a gigabyte Z68X-UD3H-B3. I am currently running at 4.5 GHz stable with a max temp of 61C at 1.3V.

    This guide helped me, it includes a gigabyte board as well.
