Ive was using a corsair h100i for the i7. Its overclocked to 4.7 at 1.340v. I was getting max temps in the 70s. Now ive ditched the aio and went custom with 2 480mm rads an ek blocks. The gpu is ok with max temps around 40 degrees but the cpu is the same as the aio. But while gaming the aio would give me temps in the 50s while with the custom loop the its still in the 70s. Ive tried redoing the block and repasting. Any answers please?
high 6700k temps

the pump is working fine, its a d5 and ive tried turning it up an down with no difference. I would know how to check the water temp. yes its plummed in correct. When i do the stresstest the cpu jumps to the 70s rather fast, like instantly really. Also when i had the aio the cpu was at 1.4v
If it goes straight to 70 then it's not water temp.
If it wasn't for your lower temps on the AIO then I wouldn't worry, but that does indicate there is something wrong.
Is the block built internally correctly with the jet plate and stuff.
Definitely got the mounting hardware correct.
If flow rate is ok and water temp is ok then it's either the block or the mount.

I thought it might have someting to do with the block. its a ek supremacy evo i didnt touch any internals just installed it straight out the box. i believe it comes standard for intel but ill double check. the cpu drops back to idle temp instanly after i stop any test. the gpu and cpu idle temps in the 20s with a room temp of 25 (small cupboard)

Hi,
I am running two 360 rads and i7 with a 4.6 and 1.34volts overclock. Also came from an corsair 110 GTX AIO.
I used to get 75 to 78 under prime on the AIO.
Now i am running top 60's and 72 on my custom loop. My titan x says nice cool at 40's under stress.
I wouldn't worry too much as our temps seem to be near enough. I went with an EK block for the cpu and i know on mine i needed to swap the jet plate for optimal cooling, but i've not done this yet using it with the one out the box.

This makes me feel better about mine. Coming from sandybridge on the same GTx 110 4.5 ghz Hottest core 58C to 4.5 ghz steady (in prime type 100% load strees tests) all even cores on skylake 75C 3.25V with the odd spike to 78C but stabilising around 75C on all cores. I guess Ill have to get used to it, or look more at this thread as I am, considering Watercooling.
From what I read the 6700k can see 10-15c drops by replacing the crap thermal compound under the IHS... Going to do some surgery on mine soon and see for myself (screw the warranty).
The fans I'm using are alpenfohn wing boost 2 but I'll be replacing these soon . I was using noctua f12 on the air so I might go back to them or phanteks. I'm tempted to delid my 6700k also. I had good results delidding a 4670k I had before this.
I could be wrong but those fans dont look like they are designed for high static pressure to perform on radiators... Worth testing some others, also checking the airflow is right. I've got 2 slim 360mm rads and my 6700k doesn't get over 45c most of the time.
Think your right about the wing boost 2. They were used in another build as air flow fans so I had them spare. I've got 2 noctua f12s sat doing nothing so I'll be picking more of these up soon. Anyway tonight I'll be delidding the 6700k as I've got everything I need from a previous delidded.
My temps are rubbish on my 6700k as well. At 1.35V its hitting about 75 running realbench, I had a supreme LTX and thought it was that, so got a Supremacy EVO gold, as it has a back plate and much better cooling apparently, but this still hits the same temps, I have 2 x 240 rads with a 780 and the cpu in the loop, the water hit about 37 degrees, the temps change very quickly, I'm a bit gutted tbh. Oh and I had wing boost 2's as well and have swapped to EK vardars, but still rubbish temps 
I'm running out of ideas now though.

Sounds like 1.35v is the top end of where you can go without delidding.
I made this video a while back. With CLU on the die you're probably talking a 5-10c drop.

This seems very odd to me, a few of us having problems with temps, considering your meant to be able to run them at 1.45V, I've seen stated on water. I even wondered if it might be my paste as the tube is 2 years old nearly (IC Diamond). But I don't think its that. Has anyone tried fitting them goofy? As I know its better on haswell-e

1.35v is already too high for a 6700k. 1.45v for anything but a quick bench run is totally out of the question.
For 24/7 I would say you're looking 1.325v max and that's under custom water and delidded.
