i am not using the default cooler. those temperatures were with cooler master evo t3
I have a system with an i3-4150 and the stock cooler. It runs Prime95 28.5 Small FFTs for hours without issues, i.e., it never goes over 90°C. Yours runs cooler with the TX3 EVO; your issue is elsewhere. If I were you I'd test with a different PSU (even though a CX430 is plenty for that system).
