So digging around in the BIOS I did not find any settings for my fan on this little Q6600 bx I am using to do secure browsing/AV scanings and such for fam.

Recently I noticed it starting to slow down a bit, and the CPU temps are around 85+. The fan isn't kicking on when it gets hot. It works fine in Windows, so I am not sure what is going on. It's a little 90mm fan connected to a 4 pin PWM connector.

I ran sensors-detect and it only finds the coretemp, no other sensors.

Any idea how to get this fan working so I don't burn out this thing?

Sensor data below:

# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# System: LENOVO 7220RY8 [ThinkCentre XXXX]
# Board: LENOVO LENOVO
# Kernel: 4.13.0-39-generic x86_64
# Processor: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz (6/15/11)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): 
Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): 
Probing for `National Semiconductor LM78' at 0x290... No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
