H60 with a loose backplate / won't do

post #1 of 7
Thread Starter 
I am testing an H60 and the backplate is too loose, as you guys can see in the photos. It does not even spread out the thermal paste properly. My specs are in my signature (the i7-3770K one).





Since this problem seems to be recurrent in Corsair water coolers I placed some washers and this is how (below) the thermal paste looks like after removing the block.





The drop in temperature was also considerable. With washers my i7-3770K passes OCCT at 4.6Ghz. Without it, obviously, does not go beyond 4.2Ghz.

NOTE: the backplate is straight as an arrow (not bent or warped), my motherboard is fine. I am testing seven coolers, including an H45, and all of them are mounting perfectly fine. The temps are very well distributed over all four cores of my i7-3770K in all seven coolers. The H60 might have a slight dead spot over the core #0 because it is generally 1-2ºC hotter than normal (I reinstalled to make sure), but nothing alarming. Everything is smooth other than the backplate gap.

Is this normal /usual for people to add washers to the backplate? Or this is a bad poorly manufactured backplate mount? I don't believe the Z77X is that thin. At least it might be the same as any H81 and H97 out there. The fan is also making noise at idle speeds (I thought it was the pump, but the pump is virtually inaudible, surprisingly). I am currently using a SP120 High Performance and it works like a charm. Temps are very good as well with the washers.

But since I'll have to RMA the fan, perhaps I'll RMA the whole unit with the backplate gap. Corsair states
Quote:
"If you have the following Hydro coolers, you might have noticed that the backplate is loose even if the standoffs are mounted. This is completely normal as the backplate will be pulled towards the motherboard once you have fully installed the pump onto your CPU"

But this does not work at all for me. Without washers my unit is prejudicial to my CPU. Things are going to get "hot" during summer down here (Brazil).

Any inputs? RMA right the way? Is the next unit come with the same gap or this varies from manufacture (they might have several manufactures making these units)? To be honest, I find it to be weird.

If im correct the washers are for exactly that reason, its totally fine to use it, as long as its even pressure on the cpu you dont have anything to worry about, ive never owned a corsair aio but check the manual that came with it, i think it should state about the washers purpose in it, but if it works fine then do it even if it doesnt say too, as long as its a solid seal with even pressure your good.

I would use washers with no problem, and I tested it (11ºC drop), but I am selling it (I just bought to test it). I can't count that whoever is buying it will be savvy enough to use washers even if I explain how to do. They could blame on me. And since the fan is also bogus I just think I deserve an RMA. My impression is that some manufactures use wrong masters. Otherwise they would have to RMA for half the line.

I already started the RMA. Let's see what they have to say about it, because Corsair states that this looseness is OK and they tell to don't use washers.

As a side note, after testing these coolers, I came to the conclusion that the mounting of the NH-U14S, with plastic standoffs and thumb screws is the best (Lucifer V2 also has it) because it does not matter the thickness of the motherboard -- you will always have a tight fit. The only problem is to tight it too much. When I installed the Lucifer V2 I did it too tight and the PC would not boot, doing loops and turning off. It was probably pinching some motherboard circuits. It scared the hell out of me. I did it again, more loose, and it went back to normal. But I know of people who go ballistic and sandwich the motherboard.

I'll let you guys know what they have to say.

Im still thinking thats what the washers are for but do come back with what they say biggrin.gif

My 2013 version of the H60 (looks the same as yours) was a little loose after securing the back plate but mine also tightened right up when I put the top screwdriver caps on. On my Asus Max V Gene with 3770k it was easy to see that it was beginning to tighten and apply pressure as the 4 brackets the screws go through started to bend down towards the motherboard. It wasn't from overtightening, it was just simply how it sucks up to spread the TIM. I did the initial mount with corsairs TIM to see how it ended up, once I was sure it had good pressure I wiped everything clean and used MX-4. Sorry you're having issues with yours, mines been pretty good to me. redface.gif

Yup, either mine came with problems or whoever designed this mounting system needs to reevaluate his / her work. Or maybe this is the cheapest they got and the engineer had his hands tied. But still... Makes no sense to approve such a mounting system. No wonder in some benchs the H60 is mediocre. With washers, my H60 debunks my NH-U14S.
