H150i Pro Installation Oddity

[Tuloth]

I just got the final component of my new build, and installed the H150i Pro.  I should mention this is my first time installing an AIO, so this may be standard and I am just inexperienced, but I wanted to run things by a few more experienced users.  I installed the backplate for the 115X mounting bracket without issue, but when I went to install the stand offs for the 115X socket, I noticed there was a significant amount of play between the standoff and the bracket, it could slide back and forth probably a few cm on the standoff.  I triple checked the installation standoffs and bracket with the instructions, it's all right.  I ended up using two of the included washers on each stand off to remove the play, and mounted the pump.  I was a little nervous about this causing the pump to be too far, but when I booted the machine didn't immediately overheat, so there's that at least.  I did notice idle temps in the low to mids 30s, which seems accurate, what had me a little un-nerved though was a max temp spike of 70 on one core while only under 10% load, I haven't tried any extensive stress testing yet.

 

My question is, is that looseness normal?  Would tightening down the pump resolve that?  Did I do more harm than good adding in the washers?  Like I said, this is my first time installing an AIO, and the components involved a fairly serious investment, so I wanted to be careful.

pretty sure you're suppose to have the washers between the board and screw when screwing it into the back plate...

Thanks for the reply, I'm afraid I'm not entirely sure what you mean?  Or possible I expressed my intent poorly.  This is the instruction page that pertains to where my issue cropped up.

 

The instructions don't indicate any use of washers here, but I inserted 2 per stand off between the stand off and the board.  Are you saying I should have used 1 on back side of the Mobo between the Mobo and the bracket?  Obviously the instructions don't indicate that, but it's entirely possible that's a better work around.

I had the exact same thing with a h100iv2 and i also thought i was being smart by using my own plastic spacers behind the motherboard, but it doesnt matter the cooler clamps down on the backplate anyway. 

 

Having said that i still dont quite get how it works, but take my word for it. Install it without the spacers and s3e if the backplate is loose even after you install the cooler. If the block doesnt rattle and is nearly installed all is fine.

Thank you @For Science!,  this is the exact sort of reply I was looking for.  When I get home today I will remount it and take it on faith that things will tighten up.  It just made me REEEEEEAL nervous.

The pump/block will apply pressure to the backing and clamp down.  The metal legs of the pump act like springs, creating the appropriate amount of tension as you bottom out the nuts.  I initially had that same pump on my 2700x build and swapped it temporarily over to the 9900k.
