Better air CPU cooling for HP Elitedesk 800 G4 SFF

[NickyD007]

Seeking more efficient tower type CPU cooler for HP Elitedesk 800 G4 SFF, 125W TDP or better, 4-pin, 4-wire 12 VDC PWM, 75 mm square screw-down mounts.  Don't care about height of unit, but MUST FIT STANDARD HP 75 mm SQUARE SCREW-DOWN MOUNTS WITHOUT REMOVING MOBO AND INSTALLING BACKPLATE OR MODIFYING FLOOR OF CASE.

@NickyD007,

Welcome to our HP Community forum!

There are no 125-watt TDP CPU HP heatsinks for the HP EliteDesk 800 G3/4/5 SFF platforms.

Best you can do without removing your motherboard, is a 95-watt TDP heatsink, with p/n: L04397-001 / L30413-001, good enough for any 95-watt TDP compatible processor, including the i9-9900K/KF and even the 127-watt i9-9900KS which I installed in my HP EliteDesk 800 G5 SFF upgrade project: Solved: Upgrading HP EliteDesk 800 G5 SFF Part II - HP Support Community - 8720291.

And you are in luck: the very difficult to find/purchase 95-watt p/n: L04397-001 CPU heatsink is currently available via an eBay Seller: For HP Z1G9 Z2G8 Z2G9 SFF Heatsink Fan L04397-001,Gen Intel 95W ENT18 S | eBay.

If historical precedent is any guideline, this heatsink will be sold out fast.
