[Build Log] My Fractal Design XL R2 full water - Page 3

post #21 of 30
I love my Fractal Design XL. Sadly, it is not the best case for watercooling. At all, really. The R2 fixed a lot of these problems, and allowed for more radiators, etc., but for my upcoming loop, I am switching cases. I am looking at the Case Labs M8, but I would have to get the pedestal. I want to use at least 3x 360mm radiators, and the XL, sadly, can not deliver. The M8 supports 2x 360mm radiators per side, so 4 in total, but I don't want anything on the front, so that limits me to 2. You sure have crammed a lot of radiators in your XL R2, though smile.gif

Subbed - looking forward to this.

I'm using 2x Samsung 840 Pro 128GB drives in RAID0 as system drive. CrystalDiskMark gives >1000MB/s sequential read and >750MB/s write. This should significantly speed up my database work since much of it is large sequential I/O. Have 2x Toshiba/Hitachi 3TB for storage and backup.

The system is set up as a single loop. Path is Pump -> Bottom Rad -> Front Rad -> CPU -> Rear Rad -> GPU -> Reservoir -> Pump
I have no problem maintaining flow (from visual inspection) since rads are very low restriction and blocks are moderate restriction.

Used FanXpert2 mobo software to manage each fan header. All Gentle Typhoons scale from 800 to 1300 RPM up to 50C then jump to max power. Pump scales from 15 to 50% up to 60C then full. Martinsliquidlab showed for MCP35X pump that RPM is essentially flat across 60-100% duty cycle. The computer is very quiet for normal loads. Can't hear it over the wind noise in Chicago. Of course it is audible when running Prime.

Well it would not appear that your loop design is the problem with CPU temps.
I have zero experience but I "hear" the 3770s can be hit-or-miss on temps, based on the heat spreader.
Have you thought of de-lidding that one or trying another?
Does not seem right that your GPU can run so cool but the CPU is smoking at load.

I have thought of delidding but am somewhat wary of destrying a $300 chip. I suppose I could always return it an try another chip. Might get a bunch of TIM and just try mounting many times.

Absolutely would scare me as well to try the de-lid.
I spend lots of dough on PC stuff but I try not to experiment with that price part.
Maybe search through the archives here a little to see if your CPU temp is out of the ordinary for the load it's under.
Since your loop water is cool enough to keep your GPU happy I see two scenarios:
1) The heat transfer is not making it from the CPU lid to the block
2) The heat transfwe is not making it from the CPU die to the lid

Any way to get a direct temperature measurement from the lid and then one from the block to see the delta?
I don't know how to do it but that would give you some idea of which transfer is failing.

Just ordered 2 pack of Indigo Extreme to see if that helps. Maybe my TIM application technique sucked. I should be 10-15C lower temp than what I have now.

Just wiped off some TIM from block and temps seem to improve a bit. I think my mounting of CPU is bad. Don't have any more TIM to try again now mad.gif .

Indigo Xtreme sucks (or I suck at mounting!!!) I very precisely matched blue rectangle to processor. I had no problem hitting high enough temps during reflow, but they never dropped as shown in the instructions. Spend half hour cleaning metal from my waterblock and cpu then tried again. This time I mounted block with slightly less than full pressure (about 3 turns from lockout). Same temp pattern.

Anyway, I figured I'd see what happens. Temps are slightly better than I had before; about 70C running Prime and 75 with IntelBurnTest. No problem with loop. Plenty of flow, fans running, water <27C (used meat thermometer in reservoir!). IBT is stable on Very High with 8 threads.

Anyone have any ideas? Or someone in Chicago willing to take a look? I'm at my wit's end.

Added 4 more vrm copper heatsinks (Enzotech BMR-C1) per HDD and dropped load temp from 36 to 32C. I know the Google test which shows temps don't really matter below 45C but I believe closer to ambient is always better.

I'm going with your CPU not being that well connected to the lid. That's it's rap I think.
Seems to me you have done everything you can.
The Xtreme profile would most likely not perform properly because the die is not being cooled well and the lid just follows the die.
I think I would search/post in the Intel CPU forum here to get some opinions.
