[Toughliquid ultra 240 not cooling]

I purchased a Thermaltake toughliquid ultra 240mm about a year and a half ago and it usually sits around 39c-49c but it recently has jumped up to 60c-70c and with a load on it its around 80c-90c I opened up the bios to check on it and it says the AIO pump N/A how do I fix this? is my pump bad and I need to purchase a new one?
