Any solutions for this?
Get rid of the app. Always overclock via the BIOS.
What motherboard, CPU cooler and power supply are you using?
MSI Z170 Gaming Pro, Be Quiet Pure Rock (CPU temps stay onder 60C without the cooler spinning at max rpm) en an EVGA SuperNova 750 GQ
Holy cow! They really overdid on the VRMs on that board. Shouldn't have any issues at all delivering steady power to the CPU with that many VRMs.
CPU cooler is enough for your current CPU.
Your PSU is not on my list of recommendations, but it's still good quality and I don't think it's what's holding you back.
Uninstall the gaming app, try your overclock in BIOS.
