i5-3450 fanless?

[Ferzerp]

Anyone passively cooling one of these? I have an Asus Maximus Gene V in a Thermaltake lanbox lite with only one of the small, back case fans running, as well as the proc fan.

The only other components are 2 4GB dimms, a Ceton cableCard tuner, A samsung 830 SSD, and a Kingwin Stryker 500 fanless PSU.

I have very little experience with fanless PC designs, but the case is somewhat roomy, and I am wondering if I can get by with a fully fanless design. Anyone have experience doing this?

I think that sandybridge produce less heat than ivybridge.

if I were you, I'd consider an i3-2xxx. I am pretty sure it can run fanless.

I've seen laptops with i3-2310 and i3-2350 run completely fanless, and the temps remained under 60c, of course when in power saving mode, and processor limited to 800mhz all the time.

In desktops, if you put a bigger/better heatsink, you could achieve better results than the above mentioned laptops.

ivy bridge does run hotter yes and to run it fan less is impossible. You'll need at least one fan

No, Sandy Bridge produces more heat because it consumes more watts.

You can run any stock clocked processor fanless and many overclocked ones as well, you just need a good heatsink. But there are no good passive heatsinks for low profile cases.

I think you should aim for cooling with a low RPM fan. In a case where there is no PSU fan to exhaust air from the CPU, you will need active cooling. I think Silverstone NT06-E should fit in your case along with a 120mm 500-800RPM fan

Correct. IB runs hotter, while dissipating less heat.

It's less a low profile case than you'd think, but the PSU is suspended above the MB, so that does cut in to the heatsink area. What I might do is take the measurements, buy that heatsink (if it fits), and then just see if it will do fine passive.

It's not like it will hurt it. The worst that can happen is throttling, and then I add a fan.

I have some experience with attempting to run fanless. Yes it works, but temps were high. Even the lowest RPM fans (120mm "quiet" designed fans running under 500RPM is pretty much inaudible for most people) will make a huge difference in temperature. So, two things of note:

1) "If a tree falls in a forest and nobody is around to hear it, does it make a noise?" Basically, does it matter if there is a fan on the CPU if you can't hear it? Especially if you still retain one of those 60mm fans.

2) For low noise, you would be MUCH better served with a totally different case with much better airflow that allows for a big tower heatsink and 120mm fan.

I would add a fan regardless. I don't think a 500RPM fan would actually make any noise you would notice, and at that point it's merely a matter of bragging rights whether your system is fully passively cooled or not.

maybe! 😉

 

[lehtv]

What I mean that it's arbitrary. I'd rather have "bragging rights" for a silent yet stable and cool system rather than a fanless system that runs very hot.
