This is a serious upgrade from what I originally had. For its price, it delivers great performance and the stock cooler seems to be decent. The iGPU is also decent, it seems to be able to actually run most of the games I want to at acceptable settings. Overall, a great CPU

No problems with this processor. I only use my Pc for web browsing at the moment and I just tested some games. In tests the temperature was going a bit high with stock fan and stock conductive paste, if I would game daily I guess I'll have to change both fan and paste.

coming from an i5-6400 to this awesome CPU, I can now stream and play most of my games at 100+ fps High settings. Everything just feels smoother.

I had been waiting for this little marvel to get to a good price point along with motherboard and memory. It was surprisingly easy to fit to the motherboard... and also the supplied cooler. Iām very pleased with the overall result. OK, I upgraded from an old bundle, but this lives up to all the glowing reviews out there, and forms is a nice speedy system. Thanks also to CCL for competitive pricing.
Easily the best bang for it's your buck for a mid range CPU. Cannot recommend it enough. Running it with a 3060ti and it works beautifully.
Very happy with the performance of this CPU despite it being a lower end core i5. Does run a little warm though especially with the stock cooler but the cooler is definitely much improved over previous generations. Highly recommend!
used in new computer build. Works as expected. EAsy to use
