Well I have removed all 6 fans and placed 80mm Noctua fans on the heatsinks. Not secured yet. It is nice and quiet, but temperatures are hitting 60.2 as highest on one so far. It is sitting on its side and open to the air, so all 4 fans are expelling the heat. I think if I enclosed it again the temps would go past 70, so may leave it like this. On a side note IPMI is very slow at refreshing information when the computer is on. Still to try installing viewer on my windows laptop.
That's intersting to know. I bought four Zalman SF-2 92mm fans to mount on the heatsinks - just waiting on the bracket design to be manufactured ......
Now runnign with 3 x 92mm Noctua fans resting in the place the intake fans were and 4 x 80mm Noctua fans tie-wrapped to the heat sinks. I set the bios to run fans at full tilt and now hitting 58 deg C. Possibly need to rethink the securing mechanism as there is a 12 Deg C differnec between the lowest and highest temps. Raid card and TV card in too. MythTV back up and running. YAY! Oh and for your mounts what type of heat sink are they for? If similar to mine I could be interested.
Oh yeah forgot to say that bit. Its about 1/10th or less the sound level as the hurricane fans. I do have 1 question though... IPMI viewer is showing overheat on all 4 processors, but sensors is showing a max of 59 deg c on one and 46 on another. I presume this is ok?
Ok uploaded a video from my phone. It is 27MB though, but hosted on my ISP web space. Not sure it does it justice though.
I tightened the tie-wraps and it must make a difference if the fan is closer to the heatsink. Now maxing at 57 deg C.
Hi Scorpuk Looking at the picture, you have the fans set to suck air out of the heatsinks. Have you tried them the other way round so they blow air into the heatsinks?
Ok tried it now and the temperature went up. Had a stable 57 deg C before flipping the fans and now hitting 62 deg C within a short time. Going to flip them back!
I have a feeling that the server is throttling the fans. In the BOIS it said 2000 RPM, but later when I used IPMI viewer it said 1000 RPM... It also sounded like the fans had reduced speed...
Well decided to stop folding for a day as the cpu temps are 61°C plus and the room is like an oven. I think I need to look at putting a fan in the room or something to shift the air out of it. Shame the window doesnt lock open a bit.
Decided to try folding with 32 cores. I thought it would balance the load between the 64 cores, but looking at temps it is using 2 out of the 4 cpu's. temp1 63.5 C temp1 60.8 C temp1 59.0 C temp1 59.2 C temp1 32.5 C temp1 32.6 C temp1 33.0 C temp1 33.0 C At least it isnt going over 65°C like it was with all 64 cores running. My TPF hasnt changed and is at 12m48s and 379,312.3 ppd, which was close to what I was getting with 64 cores. Does that mean I can run two instances of 32 cores and get 600,000ppd +? Once I get the cooling sorted out properly... EDIT: Bah it dropped. :|
Hi Scorpuk If you are running thekraken it will tie the 32 threads to the first 32 cores in sequence. If you unwrap the core then the load will spread out but you will loose all the benefits of thekraken. Make sure your Noctua fans are running at full speed. You may need more powerful fans.
Yeah I'm not sure they are running at full speed. Getting a power distriubution board for 8 x 3 pin fan connectors to a 4 pin molex. This should stop the motherboard from altering the speed. If that fails then I'll need to look at better fans. Although I thought these would be good at 31cfm at approx 17dB(A). Unbfortunately going away for a month so may have to leave it off.
Ill quite happily take it off your hands for a month and keep it warmed up Could even tune it for you and get it running sweet!
hehe. Well its running now I'm home and window is open ay 55.8°C. TPM down to under 12m and ppd up to 425,456. Wonder how long that will last.
