Reddit mentions of NoFan CR-95C Copper IcePipe Fanless CPU Cooler

I recently built a computer with an AMD A10-7870K APU and one of these. Not the most powerful thing in the world, but it's completely, 100% silent. I love it.

This is the kind of cooler you'd need to run it passively at stock clocks (or potentially with a ~200-300mhz overclock). Don't run it passively, you'll fry your CPU.

If you do want to run a passive-as-possible system, its probably possible to run a system with no fans, but it would be difficult and expensive to do. Your best bet would be to make a low power passively cooled system with an i3 and onboard graphics, and then have a separate system elsewhere on your network to stream games from.

Nono. Watercooling has fans. This. Unfortunately its expensive.
If you're not overclocking, I'd just go for the one that looks nicest and fit your case. They should all be silent enough.

You made me rethink that. I just checked how much the cables cost.

I have a hub (1 slot) in my keyboard, but it requires me to buy another cable.

The price of a DVI cable, USB for my external card and two USB extention cables for mouse and keyboard cost $35 for noname brands. They're all 10m, 5 won't be enough even to put it in the corridor. 10 might not be enough if I want to move my desk to the next room. This doesn't inclue any USB hubs, cause one slot would cost me one cable which is 10 bucks, an active multi port hub with a long cable would cost something too. Another thing is if I want to use a FireWire audio card, the cables I found in my country are $100 each, I found some $30 ones in Germany. If I want to use an internal card that would probably be even more expensive since I'd have to buy few pro audio cables, but it's kinda surprising that these digital cables that don't really need much quality are as expensive as pro audio cables (exluding the firewire ones ofc). The external soundcard of such class costs much more than internal.

I'm not sure about interference since I didn't try that, but now, when I use a computer 1m from it, I have lots of it. It's surprising that it's not present when I use the internal card and it is when I use external ones. It starts to be hearable when I plug the USB cable, when I move it it changes the pitch, so that's probably going through it.

Now, if I'd even go for the cheapest possibility I'd stil pay as much as a huge, inaudible CPU cooler costs. Add to that a quiet PSU and I'm done. If I want it completely fanless, I'd have to buy NoFan http://www.amazon.com/NoFan-CR-95C-Copper-IcePipe-Fanless/dp/B009OXB1ZM and a fanless PSU, much more expensive. Another possibilty would be switching to a low power CPU and using a cheap heatsink and a cheap fanless PSU, that's not so expensive, actually it's as expensive as an option with fans.

It seems like a good way to go if you have another room in a distance normal cables can be put through, in such case you pay nothing or few bucks and have it quiet or completely inaudible.

there exist massive passive heatsinks but im not sure how effective they are. probably should be ok as long as you don't overclock. but they're seriously huge so maybe check clearances if you're considering them.

looks like this when installed

That's not the argument here. His CPU is locked, he's doing audio recording, and his cpu has a TDP of 84 watts. If he gets a fanless Cooler like [this] (http://www.amazon.com/NoFan-CR-95C-Copper-IcePipe-Fanless/dp/B009OXB1ZM), he'd be perfectly fine because its TDP threshold is 95 watts. Also, to answer your question, yes. The 4670k also has a TDP of 84 watts. You wouldn't be able to overclock as much as a water cooler or air Cooler, but you could still get somewhat of an overclock.
