Many users have discussed issues controlling fanspeeds while using the Claymore miners.
Please check the miner profile you are using, and read the comments just before the FLAGS statement.
Here is an example:
80 # ---------------------------------------------------------------------
81 # COMMAND LINE PARAMETERS:
82 # Here is where you can add command line parameters such as intensity and mining modes.
83 # NOTE: the pool/wallet/algo settings are set by PIMP. Set those above.
84 # Default is for temp target 75C and temp stop 90C.
85 # IF YOU WANT TO MANAGE FANS WITH gputool YOU MUST REMOVE -tt 75 -tstop 90
86 # Reason: Claymore will override gputool. But we didn't want to lose the failsafe defaults.
87
88 FLAGS=-allpools 1 -tt 75 -tstop 90 -dbg -1
You have a choice with claymore, allow it to control temps... Or use gputool. If you wish to use gputool, you must remove all fan controls from the FLAGS.
Recent releases of Claymore also seem to still take control of fans on occasion. If you find your fans are not set properly, simply rerun 'gputool --config' and say yes.
You can also manually control the fans using the AMD driver. Some users have pointed to this tool as well:
https://github.com/DominiLux/amdgpu-pro-fans
In my own testing, this tool only sorta kinda works sometimes :) And a word of caution when using mixed rigs, as it simply assumes all cards are AMD. I will be forking it sometime soon and fixing it for PiMP users.
So in short, just rerun 'gputool --config' if your AMD fan control seems lost... do it while your miners are running, and everything should return to normal quickly.
We are exploring other solutions and will post here as we come up with a better plan.
Have noticed that a lot of you folks own 3D printers. And one of the common problems we all face is PCIe riser issues. Many times, all it takes is a little bump or jiggle, and things that were working for days, weeks, or months.. suddenly start becoming constant problems.
Thats where this little tool comes in. Just print a few and snap them on to the motherboard riser connector to hold them firmly into the socket. Keep in mind that this particular model will not work with all board combinations. Some motherboards will be too tightly spaced on the board, and some risers will have differing dimensions. But, the idea and model file will help you design a clip that fits your rig just right.

Good luck and happy mining!

Hello fntastik,

Hello ph75,
Sorry the forum topics were being consolidated and for some reason this forum post wan’t forwarded to it’s new merged location.
Please see following link which if you scroll you will find a number of good OC settings:

If it's of any use to anyone, I successfully modded my RX570 BIOS and adjusted timings today to get a steady 842H/s instead of the 640H/s I was getting out of the box.
Used atiflash to extract the BIOS, then just used the "One click timing patch" button to generate the new values. Saved the modded image and flashed that to the card.
That gave me 770H/s. Using this link https://linuxconfig.org/overclock-your-radeon-gpu-with-amdgpu I found that 8% overclock on the GPU clock and 14% on the Memory clock gave me a stable 842H/s
If anyone has any tips on how to increase that figure then please let me know. I'm still new to this so constantly learning.
I'm a PuTTY fan, and yes, this one looks gorgeos, however, if you are used to PuTTY, try MTPuTTY http://ttyplus.com/multi-tabbed-putty/ it will give you some more options.
two thumbs up, I have implemented this successfully on mine. You can add ./amdgpu-pro-fans.sh -s 90 to startup.sh also. for the devs it seems that claymore does not responsibly manage the fan speeds whether you take out the -tt and -tstop switches.
You will have static issues at some point because there is conductivity in that kind of plastic. Add some insultator of a kind under the mobo to ensure it lasts long.

Nice! I just discovered a large stash of 1″x2″ wood material that I want to build a test unit on. I was looking for plans for this exact thing, and here it is for all of us to review. Thanks!
