what are some average i7 920 temps under water?

that being said about the "clamping force", I did feel like after I switched brackets on my GTZ (775 to 1366) it seems like it never really clamps completely.

I completely forgot about that!....yup, that could be the problem right there

Just tell Gabe to help you out or Sadasius will make his wife blush again!

btw Sadasius...welcome aboard and SWEET looking job on your rig!!

[Sadasius]

Thanks ! Like it here very much and the people here rock!

I wouldn't put too much stock in idle temps, your load is what really matters, I suspect I need to attempt another mounting:

i7 920 C0@3.8Ghz HT On
Idle: 44/45/43/40
Load: 66/63/66/62

I am really frustrated, I had better temps with just the PA120.3 in the damn loop, I really have to assume this is a function of lowered flowrate as even at setting 5 on my pump the water is not flowing as freely as it was without the MCR220 in the loop.

What's your loop? List everything! Idle temps are a great indicator of flow problems. For instance my idle temp is 29C with OC in sig....Water temp on Pump #1 26C and #2 26.5C and ambient of 23C.

In the loop:
920@3.8Ghz
4870x2
MCR220
PA120.3
D5 w/EK X-Top Rev 2

The only addition from it's old form is the swifty rad, my temps were roughly the same and I got to run the pump at setting 3 rather than 5(current). I can only assume it's a flow issue as the res is not showing as much movement as it did on setting 3 without the MCR220. Starting to wonder if while installing the pump I accidently turned it down a few notches(hard to check).

hmm those temps are almost identical to mine. but your system is OC'd.

What rad are you ussing?

Do you have room to add another pump with the same top? If so the flow would dramatically improve. What fans are you using and in what configuration and rpm range?

[ChuckleBrother]

Scythe S-flex F's @1100RPM, previously my rig was running them at 900RPM and had better temps with the single rad....I'm sure there is something wrong here, I just don't see any way a single MCR220 could be this restrictive with my pump running full out.

Edit: While my flow MAY be lower than expected, I think I found my real issue. My fan controller(BigNG) was getting no signal and was defaulting to 50% fan speed because of this. This was resulting in 550RPM on my triple and ~600RPM on my double with my back fan not providing any fresh air to the double rad. Highest temp I am hitting now at load is 64(not going over 70 anymore!)
