Razer Core X Chroma - Can anyone confirm if the PSU fan is always on?
Hi guys, can any Razer Core X Chroma users check if their PSU fan is always powered on, especially on cold startup?
The reason I ask is - I've modded mine with a new PSU fan, however it is not spinning. The stock fan is D80SH-12 DC 12v .3A and the fan I slapped in there is a 12V .07A. I ran a quick Firestrike test, it did not spin at all (laptop has separate power, not ultrabook running on PSU power). It also didn't get very warm to begin with. Before I check wiring, I just wanted to ask current owners if they can check if their PSU fan is spinning when the core is cool and idle.
The PSU fan on mine turns on as soon as I flip the power switch. The exhaust fan next to it only starts to spin when I turn on a connected device.
Thank you very much!
I will try a fan with higher power draw first, then check my wiring. I can't use the oem fan to as I've cut the wires too short.
Interesting. Still no luck for me. I suspect it is due to you charging over the Thunderbolt 3 cable. Would you mind trying to power on the PSU without the thunderbolt 3 cable connected, and reporting if the fan spins or not?
I've tried multiple fans, up to 12V .35A, still no luck. I'm 100% certain I did not reverse the polarity of the fan wires. I'm not charging over thunderbolt, so perhaps its not engaging. I'll just have to get it up to temp and pray that it will turn on. Or watch it burn 😆
Good news, I powered the enclosure on without a TB3 cable connected and the PSU fan did not spin up. Apparently it's only when the enclosure has anything to do (including just trying to charge a powered down laptop with a full battery) that it bothers to spin that fan.
Out of curiosity, why did you replace the PSU fan? Were you concerned with the stock fan's noise?
Thank goodness! I was beginning to worry I messed something up. I ran Firestrike stress test 3 times consecutively and it still did not turn on the fan.
Yes, I can't deal with loud fans. I've stalked other threads and videos of people discussing their experience fan noise and decided to replace it before I even powered on the Core for the first time LOL. I ran the stock PSU fan on 5V USB power after I took it out, it was already louder than my liking. I picked a fan with enough CFM to do good work, while limiting noise.
Thank you for testing this for me.
Yeah it’s always on but can’t hear it.
I can’t watch any movies in my ITunes library. The video signal is coming out all scrambled pink and green glitches. Only ITunes videos are doing this and it began with this 10.14.5 Mojave update that included Airplay. Does anyone here with Radeon 56 or 64 with Razer Core X have the same problem? I’m trying to figure out if Airplay or the Razer broke ITunes.
If you have 'Prefer eGPU' set for anything that uses Quicktime then disable it. Decoding video should be done on CPU. See if that works.
In fact you should allow macOS to automatically manage everything if you are using an external display.
Thanks, I tried everything. Turn on and off Prefer eGPU, change monitors, GPU attached and not attached, reset PRAM etc etc etc. Test the GPU in two PCs etc
There is definitely a video bug introduce in 10.14.5 that exists in anything that uses QuickTime. I can play any streaming movie service in Chrome no problemo. I can’t play streaming DRM video in Safari correctly. Only unprotected videos like YouTube channels and trailers work in Safari.
I have replicated the problems you have experienced and they have always been there before the latest OS update.
That's why I only use the eGPU to accelerate pro apps. If I want to game I use a console or PC. If I want to watch movies I use a smart TV app.
@tonyvee thanks for DMing me more info and tests on your eGPU set up. It's good that users share their experiences so we can help others.
After two weeks of testing and studying many user posts, I have noticed that some Radeon RX Vega with Revision ID 0x00c0 have stability problems and video bugs. If you bought a used card that was firmware modded or used for mining then that would exacerbate the problem.
RX Vega with Revision ID 0x00c1 have a much better experience. Therefore I have refunded my Vega 64 with Revision 0x00c0.
I'll now purchase the Radeon VII but will first wait for the fan fix and for Apple to list it in their support article.
