HP mod 5cmx5cm stock cooler

[CloudStrife]

Hi,

I'd like to mod the stock heatsink/cooler on this to lower temps. There is so much room in the case, good airflow as many holes in the front and back of the case, but this tiny little cooler is a shame.

I have a "HP ProDesk 405 G2 Microtower PC". So I've done some research and found this APU is typically in laptops, and I have it in my desktop, ehh. It's socket is FT3B (BGA-769), no aftermarket coolers available.

The case is (16.5cm width), and there is a fair amount of room. But I don't know what cooler can fit, can anyone recommend me a cooler for this.

Screw position distances 5cm square for heatsink attached to mobo (fan screwed onto heatsink)

Overview:
- Dimensions 16.5 x 35.88 x 35.5 cm
- Power 180W
- APU AMD A8-6410 (2GHz, 2.4GHz turbO, with integrated Radeon™ R5 Graphics. More info on cpu in here: http://www.cpu-world.com/CPUs/Puma/AMD-A8-Series A8-6410.html
- Socket BGA769 (FT3b)


Mobo is: MS-7938 (not my image)

Removing the fan, shows the heatsink

As you can see there are 5cm holes on the heatsink where the fan was attached. And the heatsink holes on mobo are 5cm x 5cm too.

My idea was to essentially drill holes in a bracket like this, so I can fit the standard aftermarket coolers on.

Thinking on:
1. Do I add the bracket on the heatsink, or replace the stock heatsink and drill holds big enough for those larger screws.
2. Need a an okay heatsink/fan (£20/£30) with same moving bracket style or allows 5cmx5cm holes, <15cm height

My basic idea (wanted to user a Hyper 212 Evo, but it's too big, as it is same size as case width at 16.5cm)

I did ask this on tomshardware but I guess they aren't too much into modding, but did recieve some advice:
- Hyper 212 EVO will be too bulky/heavy (true, case is 16.5cm wide)
- Go for the smaller Blizzard T2, or old SK775 Intel cooler with a copper slug
- Get rid of the original cooler, but CM coolers cannot be used (they use Direct Touch technology, and embedded APUs don't have a heatspreader)
- Suggestion: modify a Zalman CNPS5X Performa, its base is slim enough to not interfere with any of the motherboard components.

I'd like to hear your thoughts and ideas, sorry for the long read, decided to put everything in this post

Are temps actually a problem to the point where there is actually going to be any advantage in lowering them. If you were trying to make it quieter I would understand to an extent.

It's a really small hole spacing for an aftermarket cooler, I can't think of any mounting system i've seen that could be easily modded that small. Perhaps a GPU heatsink might be close?

It does tend to get very warm. But overall there is a lot of room in the case, and a lot of opportunity to make it silent to with a larger (non-high pitch) fan.

As it stands, I'm just looking on ebay for large heatsinks . I'll just attach it onto the already attached heatsink with holes drilled into the fan's original position. And I'll give it some support with some metal pole touching (from heatsink to bottom of case) as to prevent sagging and too much weight on the original heatsink.
