GL-AXT1800 fan and fan connector specs

What are the GL-AXT1800

  • fan connector pinout
  • pins’ voltage & current limits
  • connector part number
  • any mechanical limitations for blower dimension
  • fastener specs if any

I plan to replace the fan. Although I’ve lowered the set temp to 50C, it concerns me to see / feel the high apparent temps, at 3144 max RPM, during mostly idle loads.

Hi

We believe that the operating temperature of the AXT1800 in your environment is not high.
The temperature measured here is the CPU temperature. In most cases, it is normal for the temperature to be below the default setting or the minimum fan start temperature (75°C, 70°C), or to exceed this in high-load or high ambient temperature situations .

Therefore, we do not recommend that you replace it.

If you still wish to replace it, please see our response below:

  • Fan connector pinout: Red (+), Yellow (FG), Blue (PWM), Black (-)
  • Pin voltage and current limits: 5 VDC, 110 mA / Max: 500 mA
  • Connector part number: Molex 5021-8600 or equivalent
  • Mechanical limitations for blower dimensions: 40 × 40 × 6 mm

Additionally, please note that disassembling the device will void the warranty.

It is likely the operating temperature is not too high under nominal factory test conditions. I don't plan on further troubleshooting the default software packages for now as more increased cooling appears to be the easiest fix for instabilities from enabling included software.

Specifically, when enabling AdGuard, the AXT1800 appear to be stuck at some of its hardware limits, with the device stuttering and losing connections. Disabling AdGuard did not stabilize the unit. Fan does not turn on at factory settings. Forcing air into the unit did temporarily stabilize, but factory resets were required to stabilize.

AdGuard setting problems elsewhere:

Before seeing the reply, I already disassembled and started summarizing.
I can't tell if 5021-8600 is an old or local PN. Molex Picoblade 51021-0400 appears to be the globally available equivalent wire housing to whatever the fan is using.

3mm wide posts limit about 14.3mm down to about 11.5mm available height

  • 105C
  • 20%
  • 2khr
  • low ESR
    But no exact matching PN, and labeling format is not 100% consistent with GJT descriptions.

Comparable 1500uF, 10V, 8mm D, low ESR or not, parts
are 20mm tall, and radial.

  • 2x fasteners, M2x0.4 x 6mm, PWH P0
  • 7x latching clips

@mkc this sounds a lot more like a resource issue than hardware issue. I have 5x SlateAX (and hundreds of customers running them). Mine consistently run 70-75 degrees on the CPU and still pull 400+Mbps wireguard tunnels smoothly.

I personally would minimize the AGH blocklists, then disable AGH and reboot before testing further.

Yeah it’s almost certainly an AdGuard blocklist resource thing imho. I trimmed down my lists and tweaks on settings in the config.yaml file. Since then my Flint1 has been stable again, and on 4.8.3 firmware.

Ah.. good to know it’s a Flint.. FYI, the Flint is the AX1800, the SlateAX is the AXT1800 (silly naming, I know).

Regardless, glad to hear it’s stabilized.
