Upgrading HP EliteDesk 800 G5 SFF Part II

[NonSequitur777]

Esteemed Forum,

This latest RAM upgrade made a difference: achieved a RAM performance score of 89.8%, tagged as "Excellent" according to UserBenchMark. This gaming rig is performing very well, including the 99.8% ("Outstanding") i9-9900KF processor score, and the 211% ("Outstanding") RTX 3080 12GB graphics card score:

This is about as good as it gets for an HP EliteDesk 800 G5 SFF, and I am closing this "Upgrading  Part II" project.

I have the Elitedesk 800 G5 SFF with i5-9600 with the 65W heatsink and when under under load from the Anti-Virus or Cinebench (Milti-core at 100%) for example, the PC is very loud and is throttling after a while. I am wondering how you managed to work with i7-9700 without the same issue.

Do you know if the CPU Socket is standard and I can replace the heatsink with some kind of Noctua? I would buy a 95W HP heatsink, but in EU they are not too many, they are too expensive.

For now I am using throttle stop to decrease the long term power limit, and PC is feeling really good.

@yavor-ivanov,

Welcome to our HP User Forum!

The reason why I got the temps for my i7-9700KF (and now the i9-9900KF) under control, is because I added two additional cooling fans (see picture), both of which are blowing air inside the case:

[EDIT:] And lest I forget to mention it, this desktop is also sitting on a Tecknet Triple-fan air cooling pad.  Keep the air going is part of the solution.

The standard/stock 65-watt CPU heatsink/cooling fan combo should work just fine with your i5-9600, as long as you improve the air cooling like what I did.

Yes indeed, I removed the top cover and the shroud and it is doing ok at top speed, reaches 72 degrees and bearably loud.

Nice small PCs, but the 65W heatsink is not designed good enough out of the box, to cover it specifications.

@DGroves,

Actually...  Just happened to see this eBay listing for a "New HP L51046-001 Omen Obelisk Liquid Cooling Fan Radiator Heat Sink" offered for just $41.35 -seriously, one of the best deals, in general, I've seen on eBay in a while. 

A quick search as per: OMEN by HP Obelisk Desktop PC - 875-1023 Product Specifications | HP® Customer Support, revealed that this AIO cooling combo was designed for LGA1151 processors, specifically the 95-watt TDP i9-9900K.

Regardless, I immediately purchased it.  Of 59 units sold, only 5 units were still available -now only 4:

Looks like I will be playing with AIO's after all.

Dear Forum,

After some reflection, I am more-or-less actively looking for an i9-9900KS -possessing a monstrous 127-watt TDP.

Only thing that is holding me back for the moment is because these processors are actually quite expensive -north of $500 on a good day, and it would mean for me to sell off some shares -at a loss, which I am disinclined to do.

Would be fun, though, to be the first person ever to fit this beastly processor in an HP EliteDesk 800 G5 SFF and see how far I can push this PC -assuming the Firmware allows me to.

Esteemed Forum,

The "New HP L51046-001 Omen Obelisk Liquid Cooling Fan Radiator Heat Sink" arrived and did not disappoint!

This HP OMEN LGA1151 AIO liquid cooler unit is indeed brand new, and certainly more robust/heftier than I imagined:

There appears to be liquid inside this unit.  I'll have to research if this AIO unit is ready-to-go, or if I have to refill it/top it off with whatever liquid formulation HP recommends.  If anyone already knows the answer to this, by all means, please respond.

Btw, because Amazon knocked down the pricing quite a bit, decided to purchase a matching Timetec dual rank 2 x 16GB RAM kit to the pair I bought recently:

your HP AIO is a sealed unit using a custom mixed glycol/anti corrosion/water based mixture  simply attach a run it

since almost all AIO kits (including OEM ones) are based off a patented Asetek  design you may be able to id the exact device in the hardware strings and download the proper software package for it however not all OEM AIO's have software, as they use preset/ fan/pump speeds

being a sealed unit there is no way to add more fluid, although it's possible to do so using unapproved methods

@DGroves,

Much obliged -thank you for the heads-up!
