Nope. This wasn't a good idea from the beginning. You aren't supposed to run K processors with the stock fan due to the increased clock speeds and unlocked bios.
Anything over 80 and the temps start to get worrying, in that they may cause damage to the CPU over time.
You need to get an aftermarket cooler.
Get the Cryorig H7 or the Coolermaster Hyper 212 Evo. Both are good fans and will keep your CPU cool, although the H7 provides better performance. Going for $35 on Newegg right now, bargain.
