Motherboard has different screw pattern than AMD proccesor!

[joeblackbird]

I purchased a HP Pavilion Gaming Desktop 690-0067c AMD Ryzen7-1700 - 16GB - 1TB HDD. Under Hp specs the PC was up-gradable to AMD Ryzen7-2700. I installed the processor with no problem, but when I tried to install the heatsink that came with the AMD Ryzen7-2700 the screw pattern did not match the pattern on the motherboard. The mounting pattern on the motherboard is in a square pattern and the pattern on the heatsink is rectangular pattern. Therefore, they don't match at all. Any suggestions?

Its specs

     https://support.hp.com/au-en/document/c05953209

It has  Form factor: Customised size: 24.4x26.7 cm (9.6x10.5 in) motherboard tat means it won't use many things as standard form factors.

Can you re-use old screws ?

Regards.

Thanks BH for the comment! I tried to get support from HP but no luck there. The Am4 Sunflower motherboard that HP uses is not a standard Am4 motherboard, as you pointed out. To solve the problem, I just need to purchase a new heatsink. I'm sure that I need a heatsink with a Intel socket configuration. I just don't know which one. I think it maybe an Intel socket 1151, but I'm not sure.  Any thoughts?

First of all why can't you reuse the same heatsink/fan assembly?

TDP is the same in both cases - 65W:

And the same heatsink/fan assembly is most likely used for all available CPU options in there?

So unless I miss something obvious you should be okay.

Failing that this chappy might possibly be suitable due to its assembly:

Alas! Review the documentation and pictures that are shown there very carefully - and check its dimensions as it's not a small assembly.

First of all, I want to thank you for your input. You are right, I think I will do as you suggest. The only reason I wanted  to change the heatsink is that the heatsink is larger and more elaborate for the AMD Ryzen7-2700 than the AMD Ryzen7-1700. And I assume the reason is that the 2700 runs hotter than the 1700.

My careful stance on this: you should be fine, at least on the face-value (i.e. based on the spec available for your MoBo).

Quite similar Intel-based story here: https://h30434.www3.hp.com/t5/Gaming-Desktops/upgrading-from-I5-6400-to-I7-6700k/m-p/7329114

Obviously it's worth keeping closer eye on temperatures once you make the swap.

Let us know how did it pan out in the end.
