Please, send me a SEND REPORT from SpeedFan's INFO tab and include this ISSUE ID number in the notes to the report.
In the meantime, run SpeedFan with

Hello, I tried the /NODELLSCAN instead of the /NOSMBSCAN - same issue.

I also added the above! Thank you.

I also have mouse lockup/skipping on beta 4.46
but I cannot click on info tab as it runs a hardware scan and causes a bluescreen with a nvlddmkm.sys file as the cause (same with closing and reopening speedfan the 2nd time)

assuming it is related to nvidia quadro/quatro as it worked before I updated to the newest Quattro FX 3450/4000 295.73 driver

on a dell precision workstation 470 (MB Model <0XC838>) with 2 dual 2.8 zeon's (4cpu's)

and for me also /NODELLSCAN AND /NOSMBSCAN did nothing (is there a /NOI2CNVIDIA command?)

the mouse will pause for 1~2 seconds before any movement requires guessing where it will stop, closing and control+alt+del speedfan will not fix the prob a reboot is required

PS I cannot upload my debug.nfo as it says i need to delete the first one as it is a duplicate

as our motherboards are different i7 vs xeon I will open a new ticket if needed

Can you upload DEBUG.NFO when using /NODELLSCAN, please?

There are two switches: /NONVIDIAI2C and /NONVIDIATEMP, but /NOSMBSCAN should prevent SpeedFan from accessing the I2C bus on those video cards too.

I uploaded the NODELLSCAN debug.nfo

If there is anything else more complicated to test out, please let me know.

Hope this helps :-D Thank you!
