My CPU idles at 45-50 degrees. Should I replace the cooler?

Goopyanon · Jul 12, 2016

Hello,
I've been concerned about my CPU temps for a while now and just want some suggestions/opinions on where I should go next. I'm currently using an Intel i7 4790k with a cheap CPU cooler (Arctic Freezer 7 Pro Rev 2) and it idles around 45-50 degrees and while gaming gets up to 65 degrees without overclocking. I am worried about damaging my CPU and I don't like how hot the PC makes my room. I have looked into other better quality coolers like the Noctua U9s and the Cryorig H7, They have to be small because I'm using the Corsair SPEC 1 case. Unfortunately the Cryorig H7 doesn't deliver to the UK so I'm really looking for other suggestions. I don't know much about liquid cooling and I'm worried about a pump leak if i get one, so air cooling would be preferred as it seems less can go wrong with them.
My budget is around £50
Anyway let me know, thanks.

The cooler isn't responsible for how hot your room is getting, its job is to remove heat from the cpu and the heat has to go somewhere. It will either stay at the cpu causing higher cpu temps or be removed more efficiently for a cooler cpu and the heat will be pushed out of the case into the room.

65c is perfectly acceptable for gaming temps, if you're looking to overclock then a better cooler would give you better temps when overclocked. The af7 is a bit of a budget cooler, better than the stock cooler but it's no noctua nh-d14 or h100i either. Keeping in the same price range will likely give you a similar cooler to what you have, 6 of one half dozen of the other. A $20 cooler for a $30 cooler wouldn't make a huge difference, not like a $20 cooler vs a $60 cooler.

What are your ambient room temps in the room your pc's in? That will have an overall effect on cooling. It's a bit more expensive than 50 sterling but something like the dark rock tf may work.

Performs like a larger air cooler while remaining pretty 'short' at 131mm tall to fit that case. There aren't a whole lot of options. Trying to stay within your budget, get better cooling from an air cooler within those limitations for cooler height is difficult. Liquid coolers are more expensive. Air coolers under 155mm will generally perform similarly regardless of cost, one a little better than another maybe but limited choices.

I expect idle temperatures to be 10-15c. over ambient if it is mounted properly.
Is the cooler on square and firm?
Did you use too much paste?

Do you do better if you take the case covers off?
Any cooler needs a source of fresh air.

Ambient room temperature is 22 degrees. Thanks for the suggestion.
