Suggestions for passive CPU cooler?

[Borna Horvat]

I can't find any, so to speak

My best bet currently is to go with Arctic Cooling Freezer 13, and then just remove the vent. Seems massive enough and resonably priced.

I'm looking to cool a Pentium G4560 with it, but in the future possibly something stronger.

Any tips?

For Passive cooling, and future use with a more powerful cpu? Le Grand Macho RT.

Any decent 120mm tower cooler will probably handle a G4560 passive without a fan if you have enough case airflow. But going with a more powerful CPU, that's going to depend on the CPU.

Scythe Ninja, Arctic M1? Noctua something?
Anyway what you mean passive cooling, no vents on the cooler but there is airflow inside the case or no airflow at all?

NoFan CR-80EH - good for upto 80w CPU and there's a review of it cooling a 3570k perfectly fine, though don't expect to overclock on any passive cooler.

I hate noise and was thinking of gradually removing all vents from the case. I'd even want a PSU without a fan, or at least with a fan that doesn't turn on unless PSU is under heavy load. I saw some fans from Arctic Cooling that don't turn on unless required, and are affordable, but those are case fans. I mentioned Arctic Cooling 13 because I was looking at weight of all the fans. It's heaviest of all single fan coolers out there in that price range.

For passive, it is not only about weight. It tends to be about wider spaces between fins that allows the heatsink to take advatage of what little airflow there is.

Stick an 800rpm fan on the cooler, they run silent and you don't have to worry about temps. I've used these fans (link below) and they truly run silent.

Not going to happen. Even those PSUs that run passively need fans in the case for airflow. It takes very specially designed cases to get entirely passive cooling.

Your best bet is to get a case that can handle several 140mm fans in the front and back/top. Then putting very low RPM fans in every spot in the front and back/top to pull air through the case, but still be virtually silent. Then use a low powered CPU and a semi-passive PSU.

If I was really after silence, I'd get the following:

Fractal Design Define S: https://www.newegg.com/Product/Product.aspx?Item=N82E16811352054
4 x Noctua NF-A14 ULN: https://www.newegg.com/Product/Product.aspx?Item=9SIAADY4B02522
Seasonic Prime Ultra 750w: https://www.newegg.com/Product/Product.aspx?Item=9SIAH417YN4763
Noctua NH-D15: https://www.newegg.com/Product/Product.aspx?Item=N82E16835608045

I'd put 3 of the Noctua NF-A14 fans in the front of the Define S as intakes, and one in the back as an exhaust. I'd leave the top panel on the case as well as the side panel cover to trap as much noise as possible in the case. I'd mount the seasonic with the fan facing in the case, so if the fan did kick on, it would help exhaust air from the case. I'd run the NH-D15 passive with no fans.

FYI, passive cooling only works if you blow hard enough (or alternatively, flap your wings fast enough), hahaha

 

[cucker tarlson]

thermalright have a passive set,it's called macho zero.not a goood idea without case fan tho.an rembember the cpu fan cools the vrm too.

1. There are fanless PSUs that work just fine. Also keeping a PC at 50% means most efficient. A 500 watt PSU with a 425 watt load burns more lectricity and creates more heat than a 850 watter at 425 watt load.

2. Phanteks remains king of the hill for silence
http://www.silentpcreview.com/article1345-page7.html

Take the Noctua fan(s) off a Noctual cooler and installow slower rpm phanteks and temps drop 3C, At the same rpm, the CPU will be 6C cooler with the Phanteks fans.

I have 16 fans and you can't tell machine is on w/ eyes closed.
