Strange Temps Overclocking

So I have a delided i7-4770K, Z97 Sabertooth Mark 1, and a Corsair H100 AIO cooler. I had my CPU overclocked to 4.3GHz on 1.283V, and it would hit between 80 and 85C when being stress tested in my Corsair 800D case.

 

Recently, I switched my system into my new NZXT H440 case. No new parts, did not detach/reattach cooler from CPU in the process. Now I'm able to hit 4.5GHz with 1.310V, and the temps are only reaching 66C.

 

Both AIDA 64 and HWMonitor are reading these temps, and the motherboard CPU socket temp monitor seems to confirm these numbers.

 

How is this even possible?

You probably mounted the cooler incorrectly in the first case. They seem too high for a delidded 4770k.

I am also getting 65-70 but with higher voltages... and the same cooler as yours.... wtf?

 

I have a 6700K running at 1.36 volts and max it hits is 67° or 70°

 

I have no clue if the case is made out of fairy dust or there is something wrong with our coolers or the coolers are just magical and they work better in the H440

You probably had a bad mount the first time around.

 

As stated before, I did not re-attach the cooler so the mount could not be the issue.

 

Try reseating the cooler and using new thermal compound, make sure it has time t set in aswell

 

If I'm getting great temperatures now, why would I reseat it?

Missed this comment in my last post.

 

It seems unlikely as I did not re-mount the cooler on the CPU when I switched cases.

Did you switch the orientation of the rad? Moving the system could have done something as simple as dislodge an air bubble in the loop, which would net you a pretty drastic temp decrease if it was stuck somewhere like the CPU block.

 

The marketing on AIO units almost always mentions, "fully vacuum sealed" but I have yet to find one I can't shake the hell out of and hear air in.

Good catch. I did indeed switch the orientation of the radiator. Maybe air was dislodged, or now I'm thinking maybe one of the lines was kinked underneath its shroud restricting flow.

the 800d was a very poorly airflow efficient case. the newer case chassis' are a lot

more air friendly. thus providing ample air to cool the h100 radiator. possible different

ambient temperature would be another variable.

sshhh I was talking about before, last night was a long night xD

Delidding provides one less heat spreader so its direct contact to contact rather contact to spreader to contact where heat isnt as efficiently transferred. Now why doesn't  Intel shipped them pre-delidded? To protect the CPU dye is the answer to that. And what the person above me or so said, perhaps a bad mount contributed to those high temps last time.

What I would also suggest is get a custom loop on that thing asap and overclock to high hell. You still have a good .04 volts worth of overclocking and .06 if you get a custom loop it'd be .09~ volts assuming temps are under control, Also I would suggest if you do intend to overclock even more go run a cinebench test and post it here! http://linustechtips.com/main/topic/62476-post-your-cinebench-r15r1152003-scores-over-500-submissions/

Haha. I actually moved it over because I'm in the process of switching over to a custom loop. Going in this Saturday. I just wanted to compare the OC I can get with my AIO to the one with a custom loop.

Delidding lowers temps mostly by reducing the distance between the ihs and the die. The ihs itself conducts heat very well and the difference between using it and not is very small.

You can't compare a 4770k to a 6700k...

Oh never mind I thought he had a 6700K :P
