This is insane, I've always appreciated your works getting smaller and smaller. Really liked the idea and just checked the prices on eBay desperately. btw, what happened to your website?
Log ThinkStation P350 Tiny - 1L Pocket Rocket Lake with RTX A2000
- Thread starter REVOCCASES
- Start date
The most recent Dell Optiplex 7080 Micro has a PCI slot option now, except it orients the GPU facing down. This might give you about half a slot height of extra space for heatsink/fans...
It looks like a JST connector of some description, I think GPU fans use JST PH (2.0mm pitch) connectors, which looks about right.
::EDIT:: Actually on second glance, it looks like a surface mount connector, which means it might be a JST SH (1mm pitch), but they're only rated to 1A @ 50V according to the JST connector wiki.
I'm suggesting they're probably a 4-pin PH as they're rated for up to 3A @ 100V and have 2.0mm pitch, with through-hole connectors. Given the P350's fan is rated at 1.5A that would lead me to assume they wouldn't be using a 1A-rated connector

Not quite, the motherboard actually extends there, so your GPU fan will be jammed between the motherboard PCB and GPU PCB.
Anyone inspired to replicate this project, Lenovo have a flashsale on Thinkstation SFF and Tiny workstations today at https://www.lenovo.com/gb/en/d/deal...=discount-percent-desc&resultsLayoutType=grid
Not sure if this might have been better as a new post, still learning the forum etiquette, but thought might be of interest to those following this project.

thnx will measure it up when my P350 arrives on MondayIt looks like a JST connector of some description, I think GPU fans use JST PH (2.0mm pitch) connectors, which looks about right.

Only if you order one with dGPU or other PCIe add-on card. Else the connector is not soldered to the motherboard. Some people who tried getting a 1650 to work with it also said the slot is limited to 55W only. But not sure...
Thanks! Website should be fixed now, some update gone wrong
I thought about it. But more as a backup plan. If my A2000 single slot mod hadn't worked out there would have been unused space on top of the CPU cooler for a slim internal PSU.
Overall the brick solution is fine for me - having the original large brick at home under the desk and the small SAVAGO GaN adapter in my backpack for the road.
Man, that's cool...
Idk if anyone has mentioned this, but HP has released/announced the Elite Desk Mini 800 G9 with a 12th gen intel and a RTX 3050Ti in it.

the 5A 12V to 5V step-down module came in today and I tested it with my 20W DYNATRON cooler... on my "test bench" it seems to work pretty well to get RPM (and noise) down... now I just hope LENOVO did not implement some kind of "fan failure checking" in the firmware
RPM without the buck:
reduced RPM with the buck:
also ordered some small thermal switches to see if I can DIY a 0-RPM fan mode for my A2000

it's been a while but I finally found some time to proceed with my "low noise" mods... oh, and I painted my single slot mod heatsink!
mod1: as mentioned before, I found the LENOVO stock CPU fan curves very annoying and the only way to get CPU fan speed down seems to be the hard(ware)-way
with the voltage step down module and some heatsink mods, the P350 Tiny is now finally dead silent in idle and even under load it's totally acceptable. Interestingly, temps are about the same as before - probably because I added some copper fins, heatpipes, etc to the original cooler - seems that makes up for the lower fan speed.
mod2: there is no way to get the fan speed on the A2000 below 3000RPM which is IMHO unnecessary, especially in idle... so I came up with the idea to make my own 0-RPM mode for it, using a small thermal switch glued to the aluminum heatsink. this switch will simply cut the power to the fan if the heatsink temperature is below a certain threshold.
for my mod I used a thermal switch with a rated "switching temperature" of 55K but this does not mean it will actually switch on/off at this precise temp. It's more of a temperature range with an "on" point at about 59C and "off" at about 46C. another issue with this solution is the fact that the heatsink temperature will not raise or drop as fast as the actual GPU temp. anyways, it works and I'm quite happy with the result. my A2000 idles now at about ~58C without fan(noise) and once the GPU reaches ~79C, the fan kicks in to keep it cool under load.
mod3: painting the heatsink with black, high temp "exhaust pipe" paint
of course this looks nice but more importantly, it dropped average temps on my A2000 by about 2~3C - not much but in such a small build every improvement counts.
sooo, I think I'm happy with the build (for now) - hope you found this interesting/helpful

thanks, glad you liked it.
