No for either. No attic and just a crawl space under the house. We have a loft bedroom and the setup is at the bottom of the stairs about 10 feet away from the bedroom with no door to the loft. I could build a box to cover it out of wood with an air intake near the bottom front and an exhaust at the back upper lip lol. Our house is like a cabin in the woods kinda setup.

LOL. In my experience with wives(had two of them), your just screwed in general.

The crazy part is that you obtain a wife in hopes of that happening... but it just ends up being the wrong kind of "screwed"! lol

My Westmere-EP DP system is running on a pair of Supermicro 1U coolers that were $10 each with free shipping on Ebay--have you looked there?

I'm always worried about the thermal capacity and noise of a 1U heatsink. The board is in a Lian Li desktop case, so size isn't too much of a concern. Sadly, there's not nearly enough airflow (and/or fin density is too high).

By all accounts it looks like a 212 evo should fit. Coolermasters site says LGA1366 mounting. The bracket that came with mine is pretty flexible. It looks like that is the oldest platform they support though.

..and $60 is slightly more than ideal. There are Thermalwright LGA771 solutions, but that's about $70 each.

The Hyper 212+ fits on an X58-based LGA1366 system at the very least--the concern I would have is the mounting. It's backplate is pretty big and thick--and often in servers there isn't much space under the board for that.

Depending on how it's done, there's either a mounting bracket attacked to the back of the motherboard, which could be removed, very carefully and with great difficulty, or it's part of the case, in which case you'd just be SOL.

Also I bet if you disconnect all of the 1U fans the board is going to have a fit.

Just means it'll flash orange. Chassis intrusion will cause all the fans to ramp up to a million RPM (edit: if it even has it. The 1750 shown below does not have a chassis intrusion switch). If the plan of action is to go chassis open with custom coolers, I'd probably suggest removing all 1U fans and remount some nice 120s top-down. It'll have a fit, but it shouldn't stop it from booting. As long as it's quiet, let it.
I have a PowerEdge 1750 in the shop. Here's a video of it just going through the basic fan cycles. When it first powers on, that's the low end. When I simulate a power failure on one of the PSUs, it kicks up in to emergency mode.

~snip~

So my Westmere system is doing quite well. It's running a pair of 92mm fans (pulled from broken C2D-era HP SFF systems) running, via PWM, at about 2400 RPM. Certainly, the noise is noticeable in an otherwise quiet room, but it's far quieter than the dual-Harpertown system next to it with a pair of 5500RPM 60mm fans.

The Supermicro coolers are these; fin-density seems entirely fine even for 95W CPUs. Obviously they don't support LGA771, so it's not a solution for you, but it's a reference of the type that works

Not enough coffee yet. Forgot to finish writing out my thought. I meant I think fin density is too high to run passively off the front and rear case fans. For testing, I have a pair of 80mm fans loosely attached to the passive heatsinks on it now. It keeps cool very easily. I think I'll just do what I can to make those 80mm fans a little more permanent.

Ahh, I thought that you meant that the fin density was too high to have a fan strapped over top, which is the point I was countering. But yes, I agree, unless it's in a 1U or 2U case exactly like it's designed for, it's hard to run just off of case airflow.

Thanks. The vids I did get to see last night were terrible and the sound quality left to be desired. It is pretty loud but not as bad as I originally thought.
Finally got to talk to the guy and I'm going Sat afternoon to get this bad boy.
@t_ski looks like I am getting the better performing model Thanks for the spec sheet. I will look into my evo mounting when I get the server home. Maybe after the challenge I will take it down and snap some closeups for ideas. As it is I will prob wait until then to really get at it for now it's get it set up install Boinc and letter go.

Sweet. Thanks Twilyth. Bookmarked. So if I install these there must be a way for the board to not to freak out.

Checking for instuctions and info now.

It looks like you need the brackets to mount that cooler. The 771 boards only seem to have mounting holes.

But on the bright side, the screws are easy to access and it looks like the backplate is insulated/rubberized

On the downside - clearances might be an issue depending on the board's design.

Just added a Q9550 @3.2Ghz Opty servers up and OS is installed and BOINC, but it won't load a project.. I'll give more detail tomorrow if I can't get it going. I still have another i5 2500k and a couple x6 1055t's I'd estimate when they are up that's about 15% of my fleet. I'm just flexing breakers at this point.. ;p

EDIT: Oh yea I have a dual processor xeon up and crunching as well.

I had the same issue with attaching a project--download and install the old version of BOINC, it fixed it: http://boinc.berkeley.edu/dl/boinc_7.2.42_windows_x86_64.exe

Aww, you know what it was working earlier with the previous version then I upgraded it to the latest version, and this started to happen.. Thanks buddy!

Yeah, I had this issue with the E5420s and also had to work through it trying to get Sealy and Panda set up--no idea why it wasn't working (I presume you had the same error about email_addr) but the older version sorted it right out

1 system UP.
1 TB HDD destroyed. it doesn't start and no RMA as its out of warranty.

 

[twilyth]

I'd try resetting the heat sink. You only need a very thin film of paste to get the job done. Putting more than that can create hot spots, so thin, even application is important.

Also make sure that the heatsink is secured as securely as possible without over stressing the circuit board mounting hardware. If you're using screws, tighten them cross-wise a little at a time to insure that you get even pressure across the cpu. Keep going back and forth until you feel you've exerted a solid amount of pressure but not so much that you're in danger of stripping anything.

I say pop the lid on the rack and let some larger coolers rise out of the top of the case.

OMG that's a heater and a half!

Can I have it? It's cold and I have 6 kids I gota feed

Man keep the fingers away!

What kind of PPD you get a day crunching with that Beast?

That's not my 4P server. Just used it to show what others have done with 2U chassis/cooling. My 4P rigs run naked(no case) and avg 25-30K+ per day with upwards to 45K on the good days.

lol.. Crazy thing is the last time I got the itch... By the end of the week I had 36 rigs crunching.. but that was when we first started... I remember @A novice telling me if I could figure out how to crunch with a toaster I would do it.. lol hence my Duron 700 @ 800Mhz... lol

I need some advice. I want to giver hell for the Crunching challenge this coming week.

I really dont know if I need to run this kind of clock with voltage or lower it to 4.6-4.7
with temps in the low 50's with 1.18v

ATM It's running a MAX of 72c on 2 cores, and 63 and 70c on the other two cores with 1.375v

Any thought's guys n Gals?

Those temperatures seem entirely fine--I wouldn't be worried about that. But my initial reaction at least is that's a lot of voltage for a 22nm chip. Personally I'd turn it down to 4.6 or so if you can drop the voltage considerably as well. Even my SB-E I have running at just 1.36V, and that's a 32nm chip.

I know the voltage is a tad high but I lost my records on my FSB OC

Just going by memory but Im going to knock it back to 1.32v Something today says thats where it used to be.

It"s Saturday morning and the Opty 6180Se rig has been running all night @100% CPU usage. It did drop to 70% momentarily, but it's solid now. I did uninstall/reinstall BOINC before cranking her up, so may that's what helped. Maybe it the lower temps of 40c she's running at with the window open? Just glad to see full utilization(that's what we pay for, right?).
