High Core i7 Temps (Water Cooling) ...

I'm not willing to run the fans flat out either, tend to stress test with them up to full speed to help ensure temperatures aren't the issue, then retest with them turned down. Time consuming though.

It might be a significant difference, or might not. Your ambients might be higher than mine, or I could have misjudged the heat load from your graphics card. Most important is that it's stable and temperatures are well under what can be achieved quietly using air cooling.

I should imagine that if I run the fans flat out the temps would go down by atleast 5-6 degrees possibly more. Plus, the 4870x2 pumps out a lot of heat, even at idle so I'm not worried about the cooling on that. I knew I was never going to get amazing temps with having the 4870x2 in the same loop but couldnt do two loops. If I drop overclock down to 4ghz with 21x191 that should lower temps a bit more also as I don't need nowhere near as much voltage. Just lose a little speed on NB and RAM though.

well i sit at 75-80c on air cooling with prime95
i7 920 D0 @ 4ghz, 1.31v

I sit at 70 (4.1ghz) with IBT and 4870x2 in loop, so prime will run a bit cooler also. I don't think my temps are that bad after doing more research. Plus fans are on half way so room for improvement.

Did some more testing last night. Two 92 rear fans on 100% - 1600rpm, 4 120mm fans on TFC quad rad at 1600rpm.

4GHZ

21 X 191

VCORE - 1.275
VTT - 1.230

IBT 10 RUNS MAX MEM

MAX TEMPS - 65 62 63 59

4.1GHZ

21X196

VCORE - 1.3065
VTT - 1.3250

IBT 10 RUNS MAX MEM

MAX TEMPS - 67 65 65 61

4.2GHZ

21X200

VCORE - 1.3350
VTT - 1.3350
IOH VOLTAGE - 1.24

IBT 10 RUNS MAX MEM

MAX TEMPS - 70 67 68 64

FANS at 1/4 turn on rad (guessing 800 rpm) 76 73 74 70

Don't think I want to keep it at 4.2. I'll try 4GHZ 20X200 tonight and then decide which one I want.

Pleased with the temps though, they seem much better and I'm sure I'll be able to get system pretty quiet in normal/gaming use.

Thanks all,

I think those temps are damn good.

Cheers! That makes me feel much better about it!

you filthy boy

i'm doing it without, i know the degradation caused by having it on is probably no better than having a constant higher voltage, but i feel more comfortable with it off... don't like the idea of 1ns 2v spikes going through my baby

LOL, I know it's dirty but I love it.

I had it on for 9 months when I had my 920 c0 and all was good. Never keep a CPU for more than a year anyway.

What is the general feeling about LLC, on or off? I guess it's a 50/50 thing.
