View Full Version : PA160+MCR220 = Fanless?

So I have a PA160, but I just bought a brand new MCR220. I was planning on redoing my loop, but now that I think about it. Would you guys think these two are enough to run a fanless system?
I'm using a CM Stacker STC-01. The pa160 will be mounted on the back of the case, and the MCR220 at the front.
Would this be enough to run 0 fans on this thing?
0 fans in the case also (well the GPU + PSU, has a fan on the bottom of it, it's a OCZ GameXtreme 600w), I'll be running an EVGA 8800GT OC.
I'm using it to just cool a e6400 (loop would be T-Line--> PA160 --> pump --> MCR220 --> CPU --> T-Line):

IMHO, you could do that but you might not be happy with the temps. You can run fans like Yate Loon DS12L at 5V and get much better temps.

I have a couple questions for you.
First, what is the desire to go fanless for? Is it to get as quiet a system as possible? If so I see you are not planning on watercooling the video card, and the fans on them stock (especially an overclocked version of one) is usually pretty noisy. In fact if you did put 120mm fans on the radiators you probably would not hear them over the video card fan anyway.
Given that, it is possible a fanless set up may work...but if you have no other fans in the case beside the psu and one on the video card I would be led to believe that your internal case temp would not be very favorable. As such there really isn't any air going over the radiators to cool it all off anyway (unless they are going to be mounted externally). Really I see your case getting pretty hot inside and doing a poor job of cooling the radiators at all.
Again I am going on the assumption you want no fans for as quiet a computer as possible. If that is the case you would be better off in my opinion to water cool the video card as well and then use some fans (like the Yate Loons suggested by the above poster) to cool the radiators. Those fans on the radiators will be quieter more than likely than just the single fan stock on the video card.

I can't even begin to express how bad of an idea it is to go totally fanless in a case not properly designed for it, even then they don't offer very good temps. Do they work?...yes, just not very good.
At least have some Yate Loon D12SL-12's on the rads pulling air out of the case. The turn over of air inside should be more than enough to keep everything cool, and with the Yates turned down, you shouldn't hear them too much (if at all).

Yea, the point is quiet. I haven't heard the fan of an 8800GT so I don't know how loud it'll be (still waiting on it). I am planning on using 2-3 yates (at least one in front and one in the back). I heard the yates today and they're quiet enough.

IMO 5 volting (or even 7 volting on fans that are already low-noise) would be better than fanless. Figure even minimal airflow is much better than none, and you can probably get 20-30 cfm @ 20 or less dbA which really ought be near silent.
Unless he plans on overclocking what difference does it make if his temps are in th 50s as opposed to mid 30s aslong as it's below the thermal throttle ?

First off, if you want fanless, it's better to attempt it with a radiator designed for passive use. Also, with a GPU fan (hopefully not stock) and a psu fan, low speed yates wouldn't be audiable over those. This isn't even considering your hdd's, and god forbid if you have a raptor.
Also, just an example, but I'm currently leak testing both my loops. Considering a MCR220 and PA120.3 feel warmer than ambient just from the heat dump from 2 D5's, I don't think your two rads would work great on an E6400

If you are looking for silence, IMO you are better off with just going passive air. It will acheive the same effect. The problem is that most any water pump (I had DDC3.2 w/Petra's top, double shock mounted) will be louder than almost any fan at 5V. Water just can't go silent unless you build isolation for your pump, and even then you can get some cavitation noise from your WB's.
I decided that I wanted super silent instead of quiet, so I switched out my LC system for a Scythe ninja, and Accelero S1. Incidentally, I ran my MCR320 fanless just for fun, and the temps that I got with that vs. my current passive air setup are very similar.
Right now I am running one exhaust and one intake @ 5v, and the loudest thing in my system by far is my HDD, even though it is mounted with rubber grommets. The instant that SSD's become more affordable and comparable in speed, I will be buying one.
Water = Quiet
Passive air = Dead silent.

iandh is right.
If your looking for absolute silence, this is not the way to go. High-end air cooling will do a much better job, since you get rid of the noisiest part, the water pump (the pump is relatively quiet, but still noisier than but not anywhere near completely silent).
Unless you go plan to overclock, go with air cooling. If you want to overclock don't get a DDC pump, the Eheim 1048 modifications offered by Innovatek and Aqua Computer are considerably quieter (might be hard to get in the US though). Also just having a fan at a super low speed on the rad will hugely decrease water temperature and the fans should be unnoticeable.
@ iandh
The noise you can hear from a DDC pump is it the same as this ?
