Note to self. When carrying the Z400 out of my brothers house for a memory slot consult with my nephew, TURN RIGHT, step down porch steps carefully!

Just think. I didn't do the above so I stumbled and fell down while exiting the porch. I have scraps, strained ham strings, the area around my right knee looks like I went at it with a dull butcher knife.

The Z400 case was dented (made some progress on straightening it out) and when the side lid popped off it took a swipe at my Gtx 1060 6GB bending the external power supply connector.

1) Z400 still boots. Running w/o side lid because it won't fit (yet).
2) Bios doesn't complain about gtx 1060 external power not being connected.
3) Driver won't load because "there is something wrong with the card".
4) Testing shows that the damaged power connector on the Z400 is not the problem.
I tested it on the Z600 which had a working gtx 1060 3GB. And no, its still doesn't work.

Contacted vendor to see if I can get a warranty replacement of the video card for dropping a computer :) Stranger things have happened :)

I had a GT 720 in there which worked well enough for me to see what it was doing. Just tried putting in a working GTX 750 Ti and nothing happened. Ran out of time, will fiddle with it tomorrow.

Major loss, I'm glad I'm not the only one.

Motherboard BIOS will rarely detect a GPU without its external power connector as this depends on drivers being loaded.

I finally have some size of heatsink numbers about the coolers that I have in my Z600 as well as a comparison with a Z400 "high performance" heatsink. I want someone to check my math because I have ordered coolers twice with the wrong sizes.

Z600 stock cooler dimensions

3 7/16" tall = 3.4375" = 87.3125 mm
3 9/16" wide = 3.5625" = 90.4875 mm
2 9/16" deep/thick whatever = 2.5625" = 65.0875 mm

The conversion of inch to mm is 1 to 25.4

Z400 high performance cpu heatsink dimensions.
In 2nd cpu slot it is too tall. in 1st cpu slot bottom heat shield interferes with the ram fan/ram plastic cover.

4 9/16" tall = 4.5625" = 115.8875 mm
3 3/4" wide = 3,75" = 95.25 mm
3 1/4" deep = 3.25" = 82.55 mm

So I am guessing a replacement LGA 1366 socket cooler might be

88 mm tall
91 mm or less wide
82 mm or more deep/thick.

Say Tom, do you have the P/N's for your parts you're describing? I still have this nagging feeling about the hi perf CPU coolers, and angled outlet fins, from when I was looking at them last summer. I just can't shake that one.

*edit* oh, and sorry about the tumble, hope the healing happens quickly. I've found that as I get a little older, things like cuts and scrapes and such don't seem to disappear quite as speedily as they did a while back... :-/

I've had a couple of these Delta 120x38mm 240cfm for years now, but they scare the hell out of me just powering them up (talk about a screaming shriek, not trying to catch them), but now they have 252cfm versions. :-O

Cheers.

Just for giggles, I checked them out on Frozen CPU, they're listed at $40, which is less than other places charge. And at least according to the spec sheets for them on that site, these 252CFM models lope along at a leisurely 7260 RPM... and _every_ review said they were LOUD, as well as: do Not buy them if you cannot accept loud, loud as a 747 at takeoff, etc. Hmm, sounds pretty crazy.

*edit* just noticed that it said these are 12v fans at 4a, do cooling fans usually run on the 12v rail, for some reason I thought that they were usually 5v. Of course, this certainly _isn't_ your typical computer fan either, though...

Z400 Hi Performance heat sink: P/N 463981-001 Just read it off the side so presume it is correct.

Genuine HP Z600 Z800 Workstation Processor Heatsink & Cooling Fan 463990-001 - This is the one I bought for my 2nd cpu in the Z600.

I believe I may have found the "holy grail" of a short of LGA 1366 heatsink! What I haven't been able to tell is if it has a higher capacity than the stock coolers? I can't find a CFM # for the stock coolers and that is the only performance # I can find on this listing.

I have put my Z400/Z600 up for sale to a "good seti volunteer" home in Cafe Seti. It now looks like it has been "modded" (its either gone or the move hasn't been finished) because it clearly doesn't seem to be there anymore. Ah, it's here in the Number Crunching area.

Just curious what type on heatsink mounts the HP Zx00 boards have. Are they an empty hole or threaded 'nut'?
The MasterCooler D-92 fits inside my old 8-5/8 inch ATX case with a little to spare. I believe I seen they are good for 130W, but that's pushing it.

EDIT: There are Intel coolers for say an i7-960 or i7-980x130W 1366 chips.

The tech installed the LCS in my Z400 he had to take out the MB to put in smaller screw in places. I can't tell if it was a "plate" or separate holes that he inserted. I do know that he returned "all" the unused hardware. And there was no "plate" that might fit below the cpu to hold the cpu heat sink.

I just looked at my Z600 and they look like they are part of the MB rather than something that was "pushed" thru. They don't have any kind of "nut" on top, holding them in place.

So I am guessing they qualify as a "threaded nut."

130w should be fine, as the BIOS will, I believe, reject any CPU needing more than that.

That sounds like my Intel board which has m3 nuts in the PCB board attached to the CPU backplate which is part of the 1366 socket. Aftermarket coolers don't have the right hardware for this. I have 3-1366 spec'd coolers, no hardware at all fits.

My ASUS 1366 has, say 3/16", holes in the board where the aftermarket backplate and extending studs through the motherboard, lets you mount risers to attach the cooler.

Was just curious as to which version the HP boards were.

Congratz! Kinda fun looking at the task manager, as well as the tasks window in BOINC, isn't it? Also, if you happen to be running coretemp, that is impressive as well! :-)

Good luck on your cooling endeavour, hopefully keeping the case open has helped a little in keeping the temps in check? Do you have a fan blowing on it?

I tried and tried and tried to get an X5680 (135w) to install on my Z600. The bio's consistently threw an error about "cpu drawing to much power".

A hint that you make too many threads?

A "Tom's Thoughts for Today" thread might be better.

130 must be the hard limit, then, as that's what the W3550's draw. Fortunately, the X5675s are 95W, vs. 135. For that, and several other reasons, the 5675 is a better choice and value than the 5680. Not enough performance improvement to justify the brain damage.

Deeper, thicker, meatier, whatever you want to call it.

Instead of 120mm x 120mm x 25mm, or 140mm x 140mm x 25mm, it would be x38mm or x50mm, or versions in between with some manufacturers.

I have a pair of 140mm x 38mm rated at 42 - 141 CFM. BTW do DO hurt when touched!

Z600 is 90x90x90mm max, with little room for error in any dimension. Might be able to get away with 100mm vertical from board.

Z400 has no real issues there, and I've had great luck with "ARCTIC Freezer 7 Pro Rev 2 - 150 Watt " and I can get them for under $20.
I will note it doesn't cool one bit cooler than the stock HP (Foxconn) cooler, due to BIOS control. Only thing to remember there with an aftermarket cooler is to ground the 5th pin if the CPU is rated higher than 80w to tell the mobo you have a high capacity cooler, else you'll get fan errors at boot.
