High 4930k Temperatures

post #1 of 11
Thread Starter 
High guys, coming at you with a bit of a concern I have. It's not serious but it is something that needs to be addressed nonetheless. I am aware that the temperature polling probes in Intel CPUs are not to be taken literally and should rather be used just as a rough idea, which brings me to my next point that the 4930k's TJ MAX is 95 degrees Centigrade.

Now this CPU is underwater on a first generation Corsair H100 and is currently slightly OC'd to 4.3GHz. With that being said, the temperature range on all the cores are about 75-85 degrees centigrade. I just got done playing a game (GTA IV which is notoriously CPU heavy anyway) and saw one core tickle 86-88 degrees. Something doesn't seem right guys, am I missing something?

I am on a Rampage IV Extreme and have the BIOS told to auto-volt the CPU as needed, could it possibly be overfeeding it? That H100 is about a year and a half to two years old and has been on almost 24/7 since then. Have I just ran the piss out of the thing to the point where it should be replaced? The ambient temperature in the case is warm anyway considering that there are 3 GTX 680s in there but I still feel this is mighty warm. Any thoughts?

would normally say just clean the rad and replace TIM... but with that kind of chip I wouldn't risk it. look around and see what kind of improvements have been made to the AIOs or you would really benefit going to a custom loop with those 680's biggrin.gif

Without doing much research, how much would you say it would cost me to do a custom loop in there with waterblock on every major processor? I cant say the thought hasn't crossed my mind...

auto voltage settings are bad

with tri SLI 680's, do you have the radiator for the h100 bringing in fresh air from outside the case?

even so, I doubt the auto voltage would account for those temps. when you seated the H100, how did you do the TIM?

Radiator is pulling fresh air in on the top mount. The TIM was applied as necessary. A small vertical stripe down the center of the IHS, matching that of the orientation of the die underneath. It wasn't carelessly applied in an excessive amount of half-dollar proportions if that is what you are asking.

At this point I am just wondering if the pump in the H100 is slowing down. I even put the pump on a molex lead all by itself to make sure it wasn't being chocked of any juice. The fans on the radiator are brand new Corsair SP series 120s, four of them in a push and pull configuration actually. They are specifically made for cooling rads, unlike the AF series.

I must say though, those 680s do make for some story worthy change in ambient temperatures. They are FTW+'s too so I have them OC'd to all hell with custom BIOS flashing to unlock the vCore. The volts are strong with this one boys...

Seriously though, how much would I be looking at for a complete loop on everything?

your radiator install is perfect then.

actually I asked about the TIM because in my experience with H70/H100 that you need to use more TIM than usual. The block of the H100 is far from being smooth and I only got good results reseating them when I spread the TIM on there attempting to emulate the way the stock TIM was there when it was new. The traditional methods of line, pea, grain of rice didn't work for me with the corsair AIO coolers.

Auto voltage is the problem. Set voltage manually at 1.2v and see what temps are

Bad mount on your h100 or the mobo is over volting on auto. What voltage are you at under load? I run off set voltage +.05 (1.36/1.344 under load LLC on high) with an h100i barely breaking 70C with fan speed around 1800rpms and 21C ambient on OCCT/LinX/Prime95.

This right here - this may have been the gold. Took the block off and reapplied a highly commendable amount (which was actually really against my inner self) and have immediately seen a 10-15 drop in Prime. Also keep in mind I am only 5 minutes into the test so these numbers are subject to change, but these numbers here are already MUCH better.

Check the AutoOV setting and it was still on auto but it was chilling at 1.275, much lower than the number it was earlier. It was in the purple earlier and now its only in the designated yellow range which is optimally normal as far as I am concerned.

Yea... that TIM though. I guess you really do need to apply a lot just like they do when they pump them out of the factory. I think this is an important message and should be more visible - I really appreciate the help guys. I knew something wasn't right. I'll start dishing out some Rep to those that have helped me.

Looks like myy H100 is fine to and is still chugging along then, I am very impressed with this device, my experience thus far has implied to me that they are a very reliable solution to a growing problem of heat. I always got made fun of in High School in my tech classes because I would always use a red system color scheme. They said red computers always run hotter and blue always runs cooler... Yea well.... I had 2 Fermi 80's at the time so I had every reason to believe them.

He thanks guys - keep it goin!

EDIT

Ok we are about 30 minutes into our Prime95 run and the temperatures have actually hit a high, a plateau if you would, and then slightly decreased. The higgest I have seen is 76 and most are hovering around about 70. That is down from the 86-90 previous venture I had. Still looking good!
