PC fans ramping to 100% after clean

[x Princess Leliana x]

Cleaned my pc (long time coming, 6 years without a dusting, oof) and after doing so the fans have been real screwy, randomly ramping up to 100% for random periods of time then back down, sometimes a second, sometimes minutes. Checked all the fan headers, all plugged in properly, fans are all cleaned, doing it on gpu  fans and cpu fan. 

 

Of note, when cleaning (especially gpu) in order to get dirt behind rear curving fanblades on on integrated heat sinks, I needed to manually move the fans while component was off, just spinning on their bearings to get access.

 

Recently its just gone full 100%, for no reason, its been stuck there for the last hour and it is deafening, hence the creation of this post.

 

What I've done:

 

Have checked speccy, all components are 30-35 degrees, 

Checked headers again, all plugged in properly

Checked fan speed curves, had a custom one in msi afterburner, turned it off and set gpu to 35% fan speed, no change.

 

Please help.

Does software say it's at 100%, and do you use any fan control software/what type of fans are they?

I would definitely start by clearing cmos. 
After that uninstall msi afterburner and install again.

Run CCleaner, or a free antivirus run (malwarebytes or avast) I had 100% fan speed before but fixed my issues using combofix back then.
