i7-920 with CPU-360

Postby Zarh2002 » Sat Apr 10, 2010 8:16 pm

I recently installed a koolance water system for my X58 system. This is my first LC system.

CPU-360
ASUS P6T6 MB block
2X VReg blocks
2X 120MM Rad (low flow Cu) with fans
PMP-450
All 13MM id tubing, all in series
FM-17 inline flow meter: My flow averages anywhere from 3.6 to 3.8 LMP.

I have the i7-920 overclocked to 4.2 Ghz (200 mhz X 21) with HT on.

Idle temps are 35C to 40C. System returns to 45C after stress in just minutes.

Running Prime 95 for 2 hours: Max CPU T = 80C
Intel Burn under max stress (4598MB): Max CPU T = 82 C

The MB temp never rose above 46C on any test.

The CPU temps seem a little high to me for water cooling. This sustem replaced a Cosair H50 CPU cooler that could not even last 5 minutes in Prime 95 OC'ed to 4 Ghz, so it is a vast improvment. Any thoughts on if I am operating where I need to?

Your cpu temp is a little high but what is the room temp? I would check the mounting pressure of the CPU 360 and make sure all screws are 15.5-75mm from the top plate(top of screw to top of top mounting plate). Upgrading your thermal compound to MX-2/3 is an option.

I have the same MB and it usually stays around 46-48c and it's using stock coolers so who knows where that sensor is.

Your OCed i7 needs more than a 2x120 rad. A 3x120 would be the minimum I would of went with. You have an option to ad another rad to the loop but that depends on the case.

Room temp is around 21 deg C. I have since lowered the Vcore down (from 1.35 to 1.33125, which is the lowest Prime stable I could get at 4.2 GHz) and have managed to improve cooling pretty well. I am now running 77 Deg C max temp on the processor. I am currently lowering the uncore voltage and seeing what type of difference it plays on CPU temp (I have a feeling it will only effect the chipset temp).

Could you expound a little more on the mounting measurements given? I put a decent amount of torque on the screws, and tightened them evenly in a star shaped patter (as well of star shape pattern a 4 post could give). I used the thermal compound that came with the CPU-360.

Yea, I would have preferred the 3x120 rad, but I had this nifty 2X120 area for fans on the bottom of the case (Thermaltake Armor +). I have room to mount 2 - 1X120 rads, so I can expand a bit.

Those temps are high based on the room temp. I'm going to guess your using Realtemp to monitor the cpu core temps?

I would install a 1x120 rad on your exhaust fan or mount a external 2x120 rad on the exhaust hole. What fans are you using on the current 2x120 rad?

Tips on CPU-360 block
-Mount the block with the outlet port at either the top or bottom.
-invest in some good compound like MX-2/3
-Tighten the screws to 15.5-15.75mm. Distance is from the top of the thumb screws to the top of the cpu-360.

Well, catastrophe struck as I posted in another thread, but in any event, I purchased some additional items which should be in this week. Here is what my setup will look like.

CPU-360
ASUS P6T6 MB block
2X VReg blocks
2 - 2X 120MM Rad (low flow Cu) with fans
PMP-450 / PMP-450-S in series
All 13MM id tubing, all in series
FM-17 inline flow meter
TMS Controller
Inline Temperature unit
2 Sets of QC's
Dual level indicator



I have both 2X 120MM Rad's installed on the rear of the case. I also removed all water blocks and applied artic silver 5 compound. My temps should be greatly improved as soon as I get this system back online.
