Extremely high idle temps

Hi I'm new to the forums. I have an Asus Rampage IV Extreme (2011) and an i7 3930k proc. Both the cpu and memory are not overclocked. (cpu-z shows clock at 3.5ghz with turbo core turned on) I'll try to make this post as short and as accurate as possible. Roughly 3 weeks ago, I updated my bios from 3602 to 4701 as I was planning on buying an i7 4930k cpu, and bios 4701 apparently supports all of the IB-E chips. The update went fine until I started noticing the cpu temp monitor was getting stuck at 79.0c. By getting stuck, I mean after I power on my computer, the temp rises and then stops at 79.0c exactly. I then tried updating the bios to 4802, but the temps stay the same.

Physically, the system is cool. The only heat I'm feeling is coming out the back exhaust of my GTX 780 graphics cards (the dual fan ones from EVGA). I have a Corsair H100 liquid cooler installed in a HAF 932 full tower with plenty of fans. The cooler feels fine, and doesn't seem to show any indication its failing either. For giggles, I even cleaned off the old thermal grease and reapplied a fresh coating. I ran Core Temp 1.0 RC6 and RealTemps in windows and both register idle temps ranging from 75c to 89c across all 6 cores.

I've tried disabling turbo core as well, but I'm getting the same temps regardless. I would have tried doing a bios flashback, but I forgot to save my old bios to a flash drive. (never thought I'd need to...lesson learned...) Any help anyone can provide would be greatly appreciated.

hmm, thats very high man, something wrong there,
should see those temps under load not idle........
so what temp are you getting idle - load ?
either the cooler is not working properly or
motherboard not reading temp properly, I would
personally think the corsair cooler is not working properly.
good luck

If either of the tubes coming from the CPU block are warm then the cooler is not working. If the cooler is connected to power...molecular or SATA connection and is working fine then maybe a temp sensor? Do you have AI suite installed? This can give screwy temp readings....corsair link? Same....

...ugh. Yeah the tubes are warm. Oddly enough I thought they were supposed to be. In fact when asked about whether or not I thought the pump was working properly, I assumed because they were warm, the pump was functioning normally. Welp...I'm kinda glad I bought that new cpu cooler. I'll try and get it installed tonight and post the results afterwards.

AI Suite has nothing to do with BIOS readings tho Arne. OP also stated he'd used Core Temp which reads DTS, if that's true, it hints at a cooler issue. OP believes cooler is not the cause tho - but everything points at that.

I'm not sure what happened to my original reply, so I'll post this again. In answer to your question Arne, yes the tubes running from the cpu block to the radiator are warm. I honestly thought they were supposed to be. When asked earlier on in this thread whether I thought the pump was working properly, I replied yes because I again assumed that was how the cooler was supposed to work. What I based that assumption on is anybody's guess. My new cpu cooler should arrive this afternoon, so I'll post the results later this evening.

Hey Jon...yeah replies are disappearing into the ether today.

The cooler actually comes to equilibrium with the room temp so while it will be a bit warmer than room temp it should feel cool to the touch or only very slightly warm...if the tubes on the pump block are noticeably warm or hot then the flow in the closed loop is not working....failed pump or blockage. Usually one of them warmer than the other...

I'd swap it out ASAP and not run the CPU in the meantime.

You know me Raja....the toast burns... I start suspecting AI Suite 😮

i checked my h100 tabs w/my calipers 12/17/11 and i found that my rear tabs were 0.04" (1mm) higher than the rest. Then i found that if i tried real hard, i could tighten the thumbscrew nuts more. So i got out the pliers and tightened them all, all the way. Now all the tabs less than 0.01" of each other's height. I redid my oc temp testing, and core0 was 6*c cooler (72*c max). It seemed to affect only cores 0 & 1, or maybe 0-2 (core 2 showed 1*c cooler), so they must've been on the rear side; the front side getting good thermal transfer contact. Cores 3-6 max temps did not change at all - they were acceptably lower from the beginning (now 72-68-64-60-64-68).

Overclocking is useless to me if it is not rock stable.

The threads on the mobo studs tend to bind the H100 bracket, as the bracket didn't fit exactly lining up W/the studs anyway. I had to bend a tab or two radially to line them up with the studs, being careful not to bend them toward nor away from the mobo.

Also, the H100 heatsink/pump unit is actually 2-peice, they snap apart. Make sure they are snapped together tightly. It appears the pump is in the HS piece, and they are magnetically coupled, to eliminate the chances of coolant leakage.

Just finished installing the new cooler, and I'm happy to report its working fine and cpu temps are much cooler. I ran a quick 20 minute game of BF4 and then Crysis 3 and at full load the highest I saw the temps go was 36c on core #2. Other, then that, its running much better. No lag at all in anything, games or otherwise.

I don't have any calipers to verify that the height of the screws matched each other. That'll be my next project, after cleaning up the rats nest that is my poor cabling job. However, I've added some pics of the new cooler installed.

Welp, I'm pretty sure this thread can be closed. Thanks again to everyone for all your advice!
