I'm dabbling in sub-zero liquid cooling. I noticed that my 2 GTX 980s won't report negative temperatures in hwinfo but will report them correctly in MSI Afterburner. Let me know if you need any special files from me.
Here is html report, debug file, and hwinfo.ini

Also probably unrelated, probably intel fault. I can't seem to detect individual core temperatures any lower than -5C. They seem to cap out at -5C
