I've recently replaced CPU air cooler (Hyper 412s) with Nepton 240M, and to my suprise temps are now worse. I'm running I7-3930K @3.8 GHz, and with 412s idle temps were ~23 Â°C which is ~3Â°C lower compared to Nepton 240M. Are these temps normal for 240M? I've never had a water cooling before, so all advices are welcome.
Images of airflow before and now. Some people advise on using radiator fans as an intake, but that doesn't make much sense to me since the hotter air is always going up and it's blowing hot air form radiator back into the CPU
