[DPS Software Warnings/Real-time spikes]

Over the past few days, I have had nearly 30 fan speed errors/warnings.

This started after the newest DPS software update.

I contacted the retailer and Thermaltake support. I returned the PSU (Toughpower DPS G RGB 750W) to the retailer. However, the replacement has given 5 warnings in the 3 hours since installation. At first, I thought it was a hardware issue - and I've either gotten another faulty PSU or there is another issue.

With each warning/error, the DPS real-time monitor shows "spikes".

 

Do anyone have any ideas on the cause of this?
