SFF PC Noctua Cooling Mod | HP Elitedesk NH-L9i Install 

Thanks for covering this ❤

I have a EliteDesk 800 G5 and have not found a fan speed control in the BIOS. I have been looking at solutions since I do use it to serve games and the heat gets out of control and disconnects users till it cools off. Which is only a few seconds. It reports only going to 80C, but I think there is a spike that I cannot see and the CPU goes into thermal for a few cycles. I think it is because the aluminum heatsink is fine for easy tasks. But if there is a spike in temp the cooler does not pull heat out instantly like a copper/heat pipe design would. I noticed the capacitor issue as well and have been shy on spending money to find a replacement cooler. This really guides me in a great direction. Thank you for posting this!

I like your content. Thank you.

I use a Noctua U12S in my x99 build cooling a 16 core / 32 thread E5-2698v3 Xeon and it works fantastic. I use that machine for editing 4k60 video from a DJI Osmo Action and editing huge amounts of raw photos and it barely hits 55c under full load.

Yeah, that shroud really helps. I just got a 600 G4 with an i5-8600 in it and have been trying to figure out some better cooling whilst retaining that, or another shroud. I wonder if the L9i you used with a standard 25mm thick fan would be better because more static pressure. You could also look at putting a centrifrugal blower fan blowing out the back of the case, might not even have to be a big one. I'll be sure to keep an eye on Your channel for more progress.

Why did. you damage the housing to geht the cooler fit in? I did drill the Noctua brackets instead from 3 to 3,5mm holes and used M3 screws to tighten the brackets to the original mounting holes in the housing. Works perfect and I didn‘t had to destroy the housing. Also swapped the i5 6500 to an i7 6700.

Upgrading from a solid aluminum mass to a heat pipe style cooler has big efficiency benefits you might only see when comparing how quickly things heat up / cool down Interesting that the BIOS fan curve seems to find equilibrium at 70c regardless of cooler, but it bet the noctua fan not doing nearly as much work as the original cooler For what it’s worth, I think 70c is great at full tilt! Especially since most home lab servers don’t spend much time up there

Just did your mod and you’re right about the power supply fan noise. Can you link to the low noise adapter?

But i had a different plan of Simply install an noctua 80mm fan on cpu cooler and back exhaust but I think your plan gives a better end result. Btw. Mine has an i7 7700. And I remember from old days. They were like fire. Even my bequiet pure rock 2 slim had problems

How about the turbine in the Mini series? I've bought Prodesk 400 with i3-8100T and expected it to be, if not a bit more quiet, the noise to be less ear drilling. Are those fans/turbines easily replaceable, beacuse the port it is connected to is signed 'P8 CPU FAN'?

Im searching atm for my first mini homelab pc. To run vms and replace a raspberry pi. What gen is good to start with?

Hi I have HP G5 8700 i7 like this I have 32G ram and looking at a amd rx7800 do u think I can go for it or will there be a lot of bottle nicking please help like to play 4k

Noctua PSU fan mod...(Only, if you feel comfortable doing so!) I recently saw another RU-vidr turn around the PSU fan on another type of sff PC to change airflow direction to press cold air into the case and drop temperatures quite a bit.

See if you can buy a Xeon E3 1270V5 ($20) for this, very cheap and slightly faster i7 6700 alternative!

Can i use this on the elitedesk 800 gen 3 TWR model?

i use a liquid freezer ii 420 for the same system :)

Does this fan fit the Lenovo thinkcentre m910s sff

If you find a way to unlock the UEFI for any GPUs and CPUs let me know.
