@tsmialek Interesting. Is that the same direction as stock? I wonder where all that exhausts. I would be inclined to "pull" air from the heat sink and make sure the intake side of equation has enough holes.
-
@tsmialek stock or with the included low noise adapter? I’m deciding between doing this or returning and eating a 25% restocking fee.
-
@aivxtla Stock. The unit seems to adjust the speed just fine with a 4 pin fan. I tried it both ways.
-
@mer It is.

@tsmialek If you have the unit horizontal, what do the temps do if you put it "turtle position" or "heatsink up with nothing above it"? In my mind (which I admit can be warped or not normal) heatsink up, fan pulling from the heatsink would be the optimal orientation. Heat rises, the components generating heat pass it to the heat sink, the fan pulls air away from heat sink. That should give a temperature gradient from the heat sink to ambient air.
Anyway, just my opinions.

@stephenw10 I restarted the unit no difference. Definitely louder than my PC that's close by.
Here is the requested firmware info.
-
OK, that's the current microcontroller code, which controls the fan.
The actual fan volume is very subjective but it seems as though yours is louder than expected. I'm not sure what we can do about that though. The only thing might be to improve the air flow by spacing it off the surface so it runs cooler and hence quieter.

@stephenw10 with room temp lowered cpu temps are at 36C and fan is slightly quieter but now sounds like it’s vibrating slightly. Still sitting on 2in spacers. I take it exchanging for a 6100 would incur a restocking fee?
-
If it's actually louder than expected because of a fault then I wouldn't expect a fee. But I don't make those decisions.
Ask on the ticket for options.
-
@stephenw10 Will do, thanks for your help so far.
-
@brachy33 how did you remove the bottom housing where the stock fan is positioned? I removed the screws and it’s attached tightly. What’s the secret?
-
@32G3LiQxu8 Honestly can't remember (it's been a while, apologies) exact steps but I do not believe it was very difficult at the time. Might of had to 'pop' it off after all screws were removed.
I would double check you didn't miss a screw and, goes without saying, be careful (don't break anything) and warranty is gone once you open. So think twice. ;-)
That being said, the 8200 max is a sweet little device that has plenty of power and has been rock-steady stable since I last plopped it in my wall rack! Running great on 23.09.
Good luck!

@brachy33 Thank you for your quick response. The screws were hidden by the desktop feet/pads. Missed 4 screws. All good now. Enjoying the silence

Notice the first picture in this thread. The heatsink has a very clever airducting design, and the chassis is not really closed as such. Those airducts on the heatsink leads to exit vents in the chassis, so it’s very cleverly designed to actually blow air onto - which is a LOT more effective in this case.
