noctua NH-u12pHELP Please

Vidar · 28 Apr 2009 at 21:27

Hi guys am putting together my new rig and have a query, just fitted this heat sink however im a little worried as the fastening brackets allow for the heatsink to move even when fully tightened and am a little worried when the tower is stood upright its not going to connect with the cpu.....

Also with the fan supplied it has a 3 pin power line when the I7 Stock fan has four pins, the mainboards fan1 controller is 4 pin! Please help!!!

The hsf problem is because of the crappy push pin design. You should get one that screws in from the back of the mobo really as the factory hsf is terrible as it is imo.

If I am not mistaken the fan can still be plugged in and you will just have one pin not in the plug, please someone correct me if I am wrong.

btw- you should have a spot for the fan on the mobo specifically labled cpu fan.

The noctua im using atm has a back plate which i installed on the mobo.... like i say im not using the Standard heatsink and am curious as to wether it should be able to wobble on the fastening brackets as it does, when the tower is upright it the noctua doesnt seem as though its connecting though you cannot fasten the brackets anymore!

The fan will connect to a 4 pin header on the motherboard without any problem, you may need to change the way the board looks at the header in the BIOS.

Is there a possibility of taking pics of the cooler, My sunbeam cooler has movement, can look at the side and see contact with the cpu - ie shine a torch one side.

Its actually too big for me to see!

Am so far not enjoying this build.... seems a lot more fiddly than the last one!

The Noctua heatsink should NOT wobble or move when fastened down. If it does, do not think about trying to turn the pc on.

So you have an i7 system, correct?

What Noctua heatsink do you have?
NH-U12P?
or
NH-U12P SE1366?

I have the first one and mounted on a socket775 board and it isn't hard at all to install. And it definately isn't wobbling and cannot be moved around when fastened.

Its the Noctua NH-U12P SE1366 CPU Cooler (Socket LGA1366) that I have installed... am really not sure what the problem is and yes its I7

IIRC, in some of the Noctua HS boxes there are different sets of fixings for different applications? A shot in the dusk, but have you used the correct bag of bits?

+1 for everything CJE says here. It should absolutely not wobble! In fact most reviews make a point of saying how good the fitting is because when you tighten the screws down they come to a stop at a point by design so you cannot over-tighten them. Double-check everything you've done before trying any power.

Ive reseated it and its still the same although it does now seem to be in contact with the cpu..... none of the screws can be tightened any further

once its tightened down it will flex on its springs if you really try to move it

otherwise i would check your temps in the bios

if you are around 30'c at stock speeds your heatsink should be on fine

Installed mine last night, no issues regarding contact.

The mounting system is the best I've used (others being CM GeminII and a TuniqTower).

I had a similar problem with mine when I build my new rig a couple of weeks ago. At the base of the Heatsink (where it fits on top of the CPU) you have to screw on two little brackets left and right which then allow you to screw it onto the baseplate under the mobo.

I had screwed mine on the wrong way, ie the brackets were on the top of the fixing point rather than underneath. (hard to describe without showing you and pointing!) The supplied fitting inistructions were unclear. Changed it and its fine with no wobble.

Might be worth checking.

Thats exactly what the issue turned out to be, id quickly emailed Noctua customer services and they sent me a much clearer diagram showing the correct fitting of the fastening brackets... did that and the issue was resolved..... the cpu is running at stock speeds at 32C so im quite happy!

Noctua should really look at changing the instructions using the much clearer diagram of the correct way to assemble and there would be no issue!
