Upgrading HP EliteDesk 800 G5 SFF Part II

[NonSequitur777]

Dear Forum,

The second 2 x 16GB Timetec-Hynix (DRAM Manufacturer: Samsung) IC U16G DDR4-3200 Dual Rank RAM kit arrived.

Installed to increase RAM to 4 x 16GB and also installed an additional 2TB Samsung 970 EVO Plus M.2 NVMe SSD increasing this desktop to hold five drives (three M.2 NVMe SSDs, one SATA SSD, and one HDD) totaling 8TB of storage, and benchmarked it.

I am somewhat disappointed that my primary (boot) drive, a 2TB Samsung 980 PRO -a Gen4 M.2 NVMe SSD, does not perform better (from the get-go) than I would have hoped for.  For reasons not well understood and not appreciated by many of its owners, Samsung has not issued a proprietary driver for this drive. I was able to 'force' a related Samsung driver to install, but it didn't appear to be any faster than the generic Microsoft 'disk drive' driver (version: 10.0.22621.1690).

Interestingly, these aforementioned upgrades did not increase my gaming rig's performance:

What is the CPU cooler you are using in that build? 

[NonSequitur777]

@Friddle,

That would be the HP p/n: L04397-001 (L30413-001) "HP Heatsink Gen Intel 95W Ent18 S / HP SPS-HEATSINK INTEL95W ELITEDESK800 G4 SFF".  I got one relatively inexpensive in the States, but they are difficult to get:

There is a Seller in Great Britain -your neck of the woods, that sells them for triple the price (gasp) I paid for it: Genuine HP L04397-001 Heatsink Gen Intel 95W ENT18 S 5059998039290 | eBay.

Thanks, that seller seems to be the only seller nearby too.

Ill see if my current cooler can handle the i9 9900k for now. 

Would this work instead? Its the HP Z4 G4 Workstation heatsink – 900187-001

It looks very similar but I don't have any of the specifications or measurements for it

*edit nevermind its way too large.

@Friddle,

The HP Z4 G4 Workstation heatsink (p/n: 900187-001) is indeed too large to fit in an SFF case, but I used an almost identical heatsink/cooling fan combo intended for an HP Z440 Workstation (p/n: 749554-001) -after some mods, mind you, very successfully in my HP ProDesk 600 G3 Mini Tower: Solved: Upgrading HP ProDesk 600 G3 MT - Page 3 - HP Support Community - 8544105.

Yea, finding a fitting/compatible 95+watt CPU heatsink/cooling fan combo for an office HP SFF has proven to be challenging. Part of my solution was/is to add one or two additional cooling fan(s), especially right over/above the CPU to substantially increase the air flow to assist cooling things down.  It has been a little bit of trial and error, but you should find workable ideas in my upgrade links that really do work but do so based on your DIY skills, and at your own volition and risk-acceptance.

My cooling solution so far has been to put 2 120mm usb fans blowing air into the front (with a removed disk drive and disk drive bezel). My method of attaching these fans is quite DIY.

I’ve also placed one 80mm fan attached where you put yours on the back of the PC, but mine is blowing air out of the case.

So the airflow direction is front to back.

This has cooled my 1650 perfectly, from thermal throttling (85C) at 80% usage to sitting at 70C at full useage.

i plan on getting the cpu cooler you mentioned and matching the front to back airflow direction. Pushing and then pulling all the hot air out of the case. I will test this configuration when my i9 9900k and motherboard arrives. And hopefully the cooling is enough

@Friddle,

Outstanding: thank you for confirming that you are an established DIY expert!

As long as the air moves/is accelerated/is funneled into the same direction, that is the way to go.

Just know that the i9-9900K(F) is a different animal altogether.  As you have seen in this particular thread ("Part II"), this processor is machine throttled at 4.70 GHz, because past this speed, it will heat up fast -as in zippity-doo-dah fast, reaching 100°C in no time flat, and then it will thermally down throttle.

So, I bought an "HP L51046-001 Omen Obelisk Liquid Cooling Fan Radiator Heat Sink" via eBay, and the idea was/is to experiment with my i9-9900KF to see if this AIO liquid cooler can provide better cooling than my current airflow-based cooling solution.  I haven't worked on this yet.

if you can find one this should also work (along with adding a case exhaust fan)

@NonSequitur777,

Interesting about the L51046-001 AIO you bought. Are you thinking of cutting a hole in the case above the CPU to place and vent the radiator?

I couldnt find many people selling the other heatsink you mentioned. Would you recommend the "Z240 Heatsink 810281-001"? I've found a few cheap internationally shipped on ebay such as the link below:

https://www.ebay.com/itm/Genuine-HP-ProDesk-600-800-G2-Z240-Tower-SFF-Heatsink-Fan-Assembly-810281-0...

Many thanks, Friddle.

@Friddle,

I am actually thinking of cutting a notch at the edge of the cover panel:

And as a matter of fact, yes, the 810281-001 heatsink/cooling fan combo you referenced would fit and be pretty effective given the airflow dynamics you described.
