New 2500K Overclocking

[FreedomEclipse]

your temps are still a little high compared to mine. my 2500k is on 4.9Ghz@1.37-1.39v (voltage is always up and down but its still stable - only retested a few days ago 10hrs prime95 stable)

CPU temps idle around 35'c and top out under 60'c. sometimes hits 61'c after 8-10hrs of prime95 but its only for less then a second before dropping back under 60'c

Nice temps. Well you do have the Kuhler 920.. I have the 620. Plus your mobo is better than mine, it's more efficient and probably puts out much less heat around the VRM then mine.

Not all 2500Ks are the same. You have a very nice chip, done well in the silicon lottery, congrats.

Ever try 5Ghz-5.2Ghz? you have room, temperature wise.

I think I attempted to get 5Ghz when i first put this beast together but it failed - I was using a TT Frio back then and temps were hitting 71'c ish. Ive not made an attempt at 5Ghz since then but i dont really need to as im not a bencher and really want to keep the volts below 1.4v so I dont put it in an early grave.

5Ghz is for pure e-peen anyway (even 4.9Ghz is for that matter - most 2500k'rs run theirs at 4.5-4.6Ghz) and theres nothing my rig cant power through like a herd of severely pissed off elephants stampeding in a rice field.

Im happy to keep it chugging along at 4.9 as the voltage and the temps are good.

::EDIT::

As a suggestion.... I recommend swapping the fans on your 620 for some 1850rpm GT's I guarantee you will see a nice drop in temps

Both of you have some very nice chips.

You telling me my dual 38MM P/P 3000RPM Scythe Ultra Kaze 120s with 133CFM each is worse then dual 1850RPM Scyth GTs?? I know the GTs have great static pressure but these thing do as well.

Both of you have some very nice chips.

Thx!

oh my bad - I didnt see you had two of them. I was under the impression that you were still rollin' with the stock fans.

your ambient temp must be pretty high if youre going over 70'c with them fans. If that was me I would have saved up a little more for a Corsair H70/80 or the antec 920 the rad is probably a little better

Yeah this is a thin rad for sure. I didn't get a better HS/F mainly because I didn't want to spend more for it. I got this cooler for $46 I wanted something better than my 212+ and this is quite a bit better.

I could have got the H100 for $100 but I don't need better temps than this really. In games/encoding I'll never hit these temps plus I may just do 4.8Ghz as my 24/7 clocks. Overclocking to 4.9Ghz and higher is just for fun.

Ambient isn't too bad. ~22C. Lots of case airflow. I just think you were lucky in getting a cool chip. I know people who got the same CPU and get even higher temps. Consider yourself lucky. Mine OCs very well but heats up. Yours overclocks well and is still running cool.

And like I said my mobo shouldn't be running this level of overclock. It only has 4 phase power..

Bit-tech.net have always recommended the 920 over the H100, not only is it cheaper but it performs almost the same which is amazing seeing as the H100 is a dual rad.

the low temps is partially down to me getting a full tower case and replacing all the stock fans for something better.

3x140mm yate loon M's
4x120mm 1850rpm Scythe GT's (2 mounted on my 920)
1x180mm Silverstone Air Penetrator

everything having its own breathing space - specially my GPUs really makes a lot of difference in temps.

as far as ambient temp goes, my room usually roughly averages around 17'c but its been pretty cold here recently and sometimes when i wake up in the morning its around 12'c in my room.

used to run a with a mid tower antec 902 V2 case. it was a decent case. but an extremely tight fit for my current set up. the fan mount on the side panel was obstructed by the rad on my 920 so i couldnt mount a side panel and things got pretty hot in there during long gaming sessions even with all the fans set to medium or turned up to the point where i could just about hear them with the fan controller.

I know the GTs are great for rads and dense finned heatsinks because of their great static pressure from their blade design but how do they fair as normal case fans? Is their cfm to noise level comparable to other high quality fans, like say the Noiseblockers?

 

[FreedomEclipse]

well ive never used a noiseblocker so i cant really comment. the noiseblockers im currently looking at dont spin as fast as the GTs but they are more quiet. sites claim that the 1500rpm noseblocker has a dBa of 8 where as the GT has 28.

you will just have the check out the reviews like me
