Hi all

I recently bought a Corsair H100. When fitting it I noticed the backplate had some plastic attached to it. I cut this off with scissors, and it really didnt seem as if it was meant to come off.

Anyway, I seated the pump block on the cpu, did up the screws in the correct order, they were all as tight as possible and all seemed fine. I tested the temps using intel burn test and prime 95, each time the temp took 20 seconds to shoot past the 100 degrees C mark.

I took the cooler off and looked at the thermal compound. If the block was split into 8 sections, only the bottom 1st section actually made contact with the cpu (I could tell as the rest of the paste was untouched and looked like new).

Is this because I removed the plastic covering on the cpu backplate?
 
Guessing you never bothered reading the instructions that came with the HSF? Sorry for the amazingly pedantic first reply but seriously, should be a warning for people who just randomly assume they can cut things off products lol -.-

Take some pictures of what you've actually done and we'll see if we can think of a way round it.

If you mean the plastic bits in each corner then yeah, you weren't meant to remove those.

I think he means the thin bit of plastic on the backplate, it just cheap thin plastic i took it off all mine, no problems. So if i was you i'd look else where for the problem, the pump may not be plugged in or even failed.

And by the way kids the instructions are ****. Before spouting out the OP is stupid.

Judging by the answers suggesting that I'm an epic noob, I don't think I explained the issue clearly.

Yes I cut the plastic film off. It was thin and covered the metal on the backplate.

Here's a picture of the current state of my H100 backplate:



The thin film went all along the X shape and around the square, it was more like a thin protective film rather than anything functional, but it wasn't peel off, it was attached to each corner via a hole around where the screws go through the backplate.

How would I know if it was a pump issue?

Its a 3 pin connector and 4 pin molex to the psu (looking into the connector on the H100 only has 2 pins not 4).

I read a post from someone with similar issues to me on the corsair blog:

Hello, Thanks Jeff & Corsair for this Blog, that's very helpfull! I have installed my new H100 in a NZXT Phantom case 2 days ago.MB is a Asus P5E, processor is a Q9550. No problem at all to setp up the radiator on top of the case. However, I have got a problem with the waterblock. Contact with the CPU is not correct, only the bottom of the block is in contact. Indeed the installation and screwing looks correct (at tried 12 times). As a result, I register internal temperature up to 70°C on 1st CPU core! This must be fixed. I just wonder why the block stays away from the CPU ... Did you meet such an issue? Another question pon H100: Do you know if it would support RPM (4 pin) fans? Thanks in advance! Shine

Is this a common problem with socket 775 cpus/motherboards? (I'm using a Q9650 on an ASUS Rampage X48 mobo)

Also there has been some issues with older mobo's, but turning the cpu block 90 degrees fixed the problem.

What a bloody joke. I can't believe I will have rotate the thing 90 degrees to get it to fit. I have the same cap layout as the gigabyte mobo in that thread :mad:

Im looking into getting a refund now, I'm fed up with it...and to think I bought a corsair 800D case just to fit the H100 into!
 
Well I gave into my inner tinkerer and re-fitted the H100 90 degrees rotated. It fits well and I'm up and running with it. CPU temps are superb under load, 10-15 degrees lower than with my corsair A70 air cooler.

I'm still annoyed, I wanted it to fit properly, but at least its working now :)
 
Just an update incase other people using certain socket 775 motherboards encounter this issue. Here's a conversation I had with a corsair techie:

Hello,
The plastic on the back plate was meant to be removed.

You might have overtightened the bracket on top of the CPU. I would just screw them up to when the screw stop turning and do not go further. Overtightened screws could cause high temp on the CPU as well. Thanks

Hi

This wasn't caused by overtightening the screws. I have a socket 775 motherboard (an asus rampage formula X48). The postioning of the motherboard caps prevents the cpu pump block attaching correctly. I had to rotate the pump block 90 degrees to get it to fit properly.

Corsair stated that this was fully compatible with socket 775, I find this unacceptable and feel that a warning should be placed on the product description that this product doesn't work with certain socket 775 motherboards.

Sorry about the inconvenience. We will make a list of old mobo socket 775 that requires cold plate mounting 90 degrees. Thanks

DO NOT remove the plastic from the backplate. As suggested this is to protect your motherboard from shorting out. I can't believe that 'technical support' assistant claimed otherwise unless they were confused with the cpu block?

DO remove the plastic from the CPU block, temps won't be too great with it in place ;).

Oh well all the those coolers with no plastic on their backplates better be recalled then, because i have plenty of them. Owns all different sorts of air coolers :rolleyes:

And i should think Corsair tech would know the different between a cpu backplate and the cpu block come on its a bit obvious.
