Help....heatsink won't install properly

Hi All,

Back again to ask more questions. Now I'm having a problem installing a CoolerMaster Hyper N520 heatsink onto my Supermicro dual Xeon Nehalem X8RDAi-O motherboard. The Motherboard already has a backplate installed, and while the holes for the 1366 heatsink correctly fit the motherboard, they won't all screw in simultaneously. I've tried using quite a bit of force with no luck.

The Coolermaster heatsink is supposed to come with it's own backplate, but there doesn't seem to be a way to install the default one. Furthermore, the coolermaster backplate seems to go directly over some important connections on the back of the motherboard, so I don't know if that would be the best way to install the system either.

Any ideas? Thanks for your help,

can you get 1/2/3 out of the 4 screws at least? are they aligned?
Most likely, the screw needs to be turned counter-clockwise instead of clockwise. This is so that the backplate screw can be retained by turning clockwise.

Yup, that's it, just figured it out by looking back at the system. Thanks for your help.

So the problem is that the backplate which came with the monitor only screws in clockwise, but the heatsink doesn't allow the screw to screw anything but counterclockwise.

So I guess it's either return the heatsinks, or remove the default backplate, which I'm not exactly sure how to do. I'm also worried because the shape of the coolermaster 1366 backplate is very weird, and looks like it's going to have metal set up directly against the wiring of the motherboard (it doesn't look insulated like their 775 plate)

What do you think I should do?

you are not suppose to remove the default backplate of the 1366. It is there to support the heavy weight of the HSF. Place the CM 1366 backplate over the motherboard backplate and screw onto the hsf.

right....that's what i had been planning to do...the problem is that the screws to the heat sink won't even fit through the holes in the motherboard, due to the clockwise screw in design for the motherboard, if you try to screw in the heatsink screws clockwise, you're fighting against the fact that it's a double screw, and the larger part of the screw is hooked into the heatsink counterclockwise

also, there seems to be a problem that the screws from the coolermaster don't exit the otherside of the motherboard backplate, and thus won't hook into anything on the coolermaster backplate

maybe i'm doing something wrong, thanks so much for your help,

~Lyuokdea

 
ok I am going to walk you through this.
Link to your hsf


Click image 5

1. On the bottom left (two bent wings) needs to be connected to the HSF by the tiny little screws.
2. On those two bent wings attached to the HSF, attach the appropriate screws COUNTER-Clockwise on to those wings.
3. HSF with two wings with 4 screws should mount onto the Motherboard.
(make sure you put in those vibrational ring on those 4 screws before putting it on the mobo)
4. screws should go through the holes on the mobo sticking out to the back.
5. Attach the top right (on the image) 1366 plate and align to the screws coming from the HSF.
6. there should be a fastener screw to mount from the back, clockwise.
 
Right....that's exactly what i've been trying to do.

I watched the video here, which is supposed to be the exact same process.

http://www.youtube.com/watch?v=XpxO2VfW1ms

The problem comes on steps 3 and 4 that you listed. On the video, they just show the guy push the heatsink clips directly through the motherboard holes. On the motherboard that i'm staring at, the four holes all have screw guides on them, they are meant to have something screwed into those holes, instead of just being pushed through, like it shows in the video and on your directions.

You can't screw anything in there clockwise, because the screws have the counterclockwise tops, and thus thew heatsink screws won't go through the motherboard, in order to be attached by the backplate in back.

I'm sorry for the frustration, it seems like maybe the new dual xeon backplates are different than the majority of LGA 1366 boards.

Either way, thanks a ton for your help, sorry this is being a pain,

i don't think that will work....because if you started screwing lefty-tighty, to get the already motherboard-tightened screws into the heatsink, then you would be unscrewing them from the motherboard. the only way to fix it, would be to turn the motherboard or heatsink around the already set screws, but you can only do that with one of the screws, not all four.

Do you happen to know of any current heatsinks that are made to screw into a motherboard (righty tighty)? It may be easier to wait a couple days and order something that i know will work, instead of trying to figure this out, and end up messing something up.

Thanks again for all your help,

~Lyuokdea

 
it's very odd for a mb to have a screw hole instead of a passive hole to clamp down. What is the point of the backplate? I find this odd as stock HSF should fit with push pin...meaning holes should be larger than screw in. I would double check the clamps/screws that came with your CM hsf.


EDIT: on that youtube, it was using the X backplate, you are aware that it's for 775 mb right? You have to use the rectangular one.

Right....the coolermaster tech support guy had sent that to me, because he said it was the exact same process, but with the different backplate.

When you say the stock HSF could fit with a push pin. Would you mean that any heatsink that uses a push-pin design should fit with this motherboard natively? (Using the screws for the motherboard backplate?) If so, is there any one you would recommend?

Thanks,

Backplate on the MB should be attached when you bought the MB.
Retail HSF (intel) has plastic push pins instead of the screws so it should go right in and lock. That is why I said it was hard to believe that it was screw hole.
Can you maybe take a pic of your mobo closeup near those holes?

is this backplate similar to yours? meaning permanently attached when you got it.

Here are the closeup pics of the motherboard, the attached backplate is shown pretty clearly on the 4th picture

it looks like the review on newegg said he got a noctua heatsink to work, but he had to go buy 3mm screws to attach it to the motherboard. I assume he just used the backplate that came with the system then...is that safe?

~Lyuokdea
 
can't use your cm hsf unless your mb backplate comes off. I wouldn't recommend removing that backplate.
You need a spring screws hsf to put this in.

if you want good cooling but cheap, use this
Text

or you could get
zalman 9700 with their adaptor kit.
 
And then you would just use the motherboard backplate, as opposed to adding on any 1366 backplate that came with the heatsink?

Also, why did you remove the noctua heatsink, will that not work?

Thanks,

~Lyuokdea
 
yeah keep the mb backplate and use the spring screw to screw it in.

I think the Noctua uses similar setup requring CM backplate.
 
So it looks like the 9900 should work, from the flash animation here:

http://www.zalman.co.kr/ENG/pr...oduct_Read.asp?idx=333

Is this the same system as the 9700 uses if I buy the 1366 mounting bracket?

But I'm not sure if it's really worth the extra money I'll be spending, compared to the Thermaltake solution. However, with the Thermaltake, I'm worried about the noise, because it looks like it's built to be on a server, and thus they probably don't worry about the noise much with that fan. Also the Zalman sounds like it is also quite loud, though it does seem to keep things quite cool:

On Xeon SMP setups I've never used a backplate - the heatsink bolts right through the motherboard into the chassis. I cannot see the pictures on the newegg link - their server must be messed up!

it seems like the motherboard might be set up like that, however, since it is an EATX board, I have a full tower case, instead of a server rack (this is being used as a personal workhorse computer, and not a server) so I won't be able to bolt anything all the way through into the chasis (unless i drilled holes)

For the servers that you've worked with, would they be compatable with the push pin design? (with the screws going directly into the motherboard with already existing backplate, as opposed to into the desginated backplate for the heatsink?)

Thanks,

~Lyuokdea
 
It seems like the dark knight heatsink should work, it has a spring screw system, but as long as the installed backplate has the correct size of screws (is there any way to check this, or anybody who has the heatsink and could tell me the size), then i think it would work really well, otherwise,

i can go with the 9900, but that's going to cost an extra $50 (for two of them), and from the technical details, it doesn't seem like the Zalman really offers any advantages for the much bigger price

Thanks,

~Lyuokdea
 
dark knight would work. You don't need their backplate for your mobo though.
it's a better cooler than zalman...good luck!

All of the ones I've seen use a bolt through heatsink. The socket 604 in the past had stock ones that had plastic pieces that bolted to the motherboard and these clips that held the heatsinks on by each end. Those were strange heatsinks made of Al with copper fins in the center.

I think it's the motherboard with weird holes...never seen this before. If you can access the image on newegg, it shows the mb has tiny screw hole instead of the normal bolt holes.
