[Ibot213]

Hey I want to uprgrade my cpu cooler with a noctua nhu12s and I want to know if the backplate is removable and how do I remove it it seems to be glued on there. The motherboard is the memphis2-s the noctua backplate can not be installed until I remove the stock x plate.

Greetings,

Welcome back to the forum.

I am not a HP employee.

You should be able to gently remove the CPU factory back plate. It could be glued if it is not screwed in. You will have to pry it if it is glued in. I don't know why it would be glued but you never know.

I see your chassis width is 165 mm. The Noctua height is 158 mm. Not much room for tolerance (7 mm).

Did you verify the Noctua fits?

I actually swapped chasis in order to fit a gpu and it does fit

thsi is what the backplate looks like if you were Wondering https://linustechtips.com/main/topic/1055095-will-it-fit-on-a-hp-3500-pro-motherboard

Hi,

 I saw the images at Linus.

I don't know what to tell you.

The screws on the MB back plate don't look like Torx screws.

As someone pointed out in that forum, you need the Noctua back plate to install the Noctua CPU heat sink.

I saw a video on YouTube we’re someone didn’t use the back plate but instead used 12mm m2 screws to mount it and it aperantly worked

Hello

I managed today, to mount the Noctua NH-U9S on my HP 0685no gaming AMD Ryzen 7 3700x. 

The stock cooler could not cool the cpu properly, even when the cooler was at max rpm, the cpu was  95 degrees celsius when video decoding and heavy gaming, the stock cooler is crap. 

I managed to take of the "intel" backplate, which was glued to the back of the motherboard, i used som time to slightly but firmly,  wiggle it off (got between the motherboard and the backplate with a screwdriver!!! )

Don't do this if you don't know what you are doing...

I had to use the "intel" installation guide with the noctua backplate, could not use the AMD solution eventhough my CPU is AMD.. 

And now it's working great, heavy load is just about 70, degrees celsius   and idle around 35.

If you want pictures i can get some.

Kind Regards
