Question

Razer Synapse no longer reads CPU/GPU temps for Hanbo AIO


LeFluffySquirrel

I had this problem as of the last two updates to synapse where synapse no longer pulls CPU and GPU data such as Temps and Speeds. Because of this my Hanbo AIO and PWM fans no longer adjust to the fan curves I have set. They still read the fan and pump speeds as well as liquid temps, but nothing else. I have already contacted support but was unsuccessful in getting a good answer. I have completely wiped and done a complete clean install of razer and all peripheral software, but that too has yielded no results. Anyone else have this problem and was able to fix it?

Edit: I have updated to the latest Windows 10 Version, as well as BIOS and AMD Adrenaline drivers 

Setup

Operating system: Windows 10 

Motherboard: ROG Strix X50-E Gaming WIFI II

CPU: AMD Ryzen 9 5900X

GPU: AMD Radeon 6700 XT

Cooler: Razer Hanbo AIO 240mm ARGB

Fan controller: Razer PWM PC Fan Controller

Razer software: Razer Synapse 3

I have the same problem.  I tried contacting support as well and nothing was solved.  After one of the Razer software updates it began working again.  The very next update it stopped working again.  I’m able to get temp and speed without issue from HWiNFO64.

Yeah thats the exact problem I’ve been having. Same CPU too. I wonder if anyone else with the same CPU or similar is having the same problem. I’ve contacted support several times and its always the same thing. I’ve given them the same info several times. One update fixed the problem until synapse crashed and went right back to the same issue

Hello,

 

I’m having the same problem with the Hanbo 240mm. No CPU Temp or Speed reading. Everything else works well.

Same here, have the latest Razer Synapse version 20240829 and both CPU and GPU show 0 degrees. I am running Windows 11 23H23 with the latest updates from August 2024. Also Windows tells me now that the Synapse driver could no be loaded because it is vulnerable and I would need to turn off Memory Protection. Can this be fixed please ?

having the same issue as everyone else with my razer hanbo it doesnt display cpu temp for fan speed. will this ever get fixed?


bizzoneOrchid101

Had this problem myself, and had some success sorting it. From what I’ve gathered, it’s possible Windows is seeing some Razer drivers as potentially dangerous. By going to “Windows Security” in system, next “Device security” then “Core isolation details”, you can turn off Microsoft Vulnerable Driver Blocklist.

This did get my temp and cpu back up on Razer Synapse 3, however synapse updated today which has taken out the CPU speed. I still have the CPU temp, so at least the fan speed curve works as expected still.

*Footnote, @razer please fix your software. What is the point of selling hardware that your software struggles to maintain. This issue has been a problem far too long.

It’s reading my cpu temps after a clean install and everything works expect the fan curve or advanced setting with the fan controller. AIO fan curve works, just not the one for case fans. I have Razer case fans and Razer fan controller. Please fix!
