NH-D14 High temps??

post #1 of 21
Thread Starter 
Am playing with my 2500K and am searching for a stable 24/7 overclock. Id like to be around the 4.8 to 5 ghz but i have been having issues with temps reaching 90c on 100% load.

So far i have been able to run IBT on MAX at 4.9ghz @ 1.46V. My voltage seems reasonable but then the temps shot up to 90c and hover around 80-90 during Burn. I dropped bacck to 4.8ghz and 1.45V and temps still in mid to high 80's.

I thought the D14 would be able to handle these speeds on a 2500K. Do you think i have a thermal compound issue. I have just got some Arctic Silver 5 and will see if this helps matters.

I think those are good temps for IBT. General use should be in the 70s.

Also, Intel's recommended max voltage is 1.4v.

Might want to back off a bit on that OC. That's a lot of voltage for 4.8-4.9. You're only going to be able to go so far on air.

I originally had a D14 on my current build but I was getting low to mid 80s at 4.8GHz/1.36v. I found that the way my D14 was mounted (since my motherboard is rotated 90 degrees) it wasn't making the best contact. When I put more pressure on the heatsink, things got a little better by about 3C.
Make sure you've got everything tightened down as much as possible.

I eventually just said F it and went with the H80. My temps are much better now.

1.45-1.46v are too much for 24/7, you want to keep it under 1.4v (possibly 1.42v). So lower your OC to what ever is stable at those volts, at least for 24/7 use.

As for you temps, they seem ok considering the high voltage and the stress test used. What are your ambient/case temps like?

I didnt realize 1.45V was concidered high for a 24/7 oc. I have read they should be fine up to 1.5V for 24/7!! Well anyway i dropped back to 1.40V and its running IBT ok temps are down to 80-82c which looks a bit better.

well mine 2500k runs 4500Mhz@1.344-1.352v
I have D14 with ap14 as push (1200RPM) middle TY@700 and top p14@700RPM
ambient 28C, IBT=71C

LOL.....

Anyways......That is actually a quite decent voltage for a 4.9 OC you have an above average chip, nowhere near "golden" but that is actually a very decent voltage for 4.9....I hate when people tell people crap like this....

I have been running 1.435 on my 4.8ghz OC since January....and there is no signs of degredation on my chip.

I even run a whopping 1.535v for my 5ghz OC and same thing, ok now if the OP was running 1.4v for a 4.0 oc then yeah , but even then he would be fine for months to come......I have run prime for hundreds of hours on many different overclocks and yup, you guessed it no sign of degredation....


OP your temps are fine and your voltages for 4.9ghz are also decent. Please take anyone telling you that your voltage is not safe with a grain of salt.

Temps in the mid to low 80s are fine when running synthetic tests, becuase nothing in the real world will even come close, its the low to high 90s you want to raise an eyebrow at, that is when your chip will start to be throttled down, and even then that usually wont happen until 98c, i should know, i have forced my chip to throttle to find out exactly when it will do so.
These chips are extremely resilient, and i will be one of the people who will tell you 1.4v-1.5v is perfectly safe for 24/7 use if you have manageable temps, and i know a guy that would back me on that who is the founder of the Sandy Stable club, Munaim1, and Munaim1 knows SB extremly well.

The OP said he's hitting 90's and you're saying that's fine? Hitting 90C isn't the end of the world but if he's going to be running that voltage 24/7, I'd tone it down a bit.

Idk He said he is shooting for 5ghz. Most the overclocks in that range that ive seen on 2500k,s are pushing 1.47v absolute max is 1.52v
so i say your temps are you main issue. ( JUST MY OPINION)

It is something to raise your brow at, but synthetic testing is taxing on the chips, reaching 90c is expected at those volts for that OC. Especially on air, you can run your chip at 90-95c without risk of damage. Now 95c and above you will start to throttle down to lower clocks, and higher than that will shut down your pc to prevent damage.

With a good low ambient i can run 1.535v 5.0ghz for 12hours in prime (that is where i choose to stop my blend at) and i will stay hovering at around 90c, given that i have a crap chip and need this much voltag for 5.0ghz.

With a hot ambient my chip will self throttle at aroun 95c and shut down at 98-100c to prevent damage. Thus, OP, control your ambient as much as possible, and you will be fine. If you can lock out a 12 hour run in prime to finish the blends you have a stable OC in my opinion, any clock i have tested at 12 hour stability in prime have NEVER given me BSODs associated with my core voltage.
