Prodesk 400 G4 CPU cooler upgrade

[Livez]

Hi,

I would like to upgrade the cpu cooler cause the default one is very bad, is that even possible?

ive see some other post that some HP Motherboard is not compatible with aftermarket cooler cause of the holes.

Desktop: https://support.hp.com/us-en/document/c05366439

Motherboard model: 911987-001

@Livez,

Welcome to our HP User Forum!

I do agree that the "generic" 65-watt TDP CPU heatsink/cooling fan combo is not as robust as it could be:

Interestingly, this CPU heatsink (p/n: 863480-001 "Heatsink - Gen, 65W, ENT16 MT") is also found to cool 8th-gen Intel processors in the HP ProDesk 400 G5 Micro Tower.

Now, a CPU heatsink upgrade option for your desktop, in my opinion, would be this one with p/n: 810281-001:

You can see one for sale via eBay (US: if interested, you may want to find one closer to home): https://www.ebay.com/itm/234899836583?epid=18026604713&hash=item36b11f0ea7:g:Hj4AAOSwRVReYUNY&amdata....

Even though this CPU heatsink/cooling fan combo is also rated at 65-watt, it cools a lot better than the "generic" version.

Hope this was helpful.

Thanks for your reply, I need a backplate replacement for the 810281-001 or default one is good?

Also can you tell if there another part number for EU market cause can't find them in EU?

@Livez,

Unfortunately, I looked around for this part in the EU, but to make a long story short:

@Livez,

And by the way, what part are you referring to as the "backplate replacement"?

for the new air cooler i need to replace motherboard backplate?

[NonSequitur777]

@Livez,

If you mean to replace the fan duct for your current CPU heatsink (which wraps around your heatsink):

With HP p/n: 908997-001 "P fan duct ENTL17-SFF", you don't need that with the upgraded heatsink/cooling fan combo.  As a matter of fact, it probably won't fit with the other heatsink anyway, and you certainly don't want it with the 810281-001 heatsink/cooling fan combo.

No i'm speaking about motherboard backplate.

Aslo can you tell if i can put thermal paste with the 810281-001 heatsink, cause it looks like he come with a thermal pad. 

[NonSequitur777]

@Livez,

You do not need a different motherboard backplate.  I can't think of any reason why you want to change out this part anyway.

You could choose to use the thermal paste as provided with the heatsink, personally, I would clean it off and use my own -better quality thermal paste, such as Arctic MX-4.

Thanks for all you information, i will order the 810281-001 heatsink.

Also do you think it will fit in my Prodesk 400 G4 Micro Tower? cause the  HDD/DVD bracket is very close to the cpu position.
