Oh god. Please tell me you are kidding. Please.... please...

A computer will dump exactly the same heat whether it works at 30ºC or at 50ºC (well, not exactly, but I'm not going to talk about efficiencies as its cumbersome). So, no. Please check back your basics, you could make use of them. At the end of the day a computer eating 300W is a computer dumping 300W of heat. It doesn't matter if its liquid cooled, or air cooled, or not cooled at all, the heat is there regardless***


***provided you don't have the radiators in a different room, that is.

You are making a mistake believing the core temp of your CPU will translate into increased temperatures in your room. The issue with "space heater effect" would be the idle thermal energy in watts and how much of that is being dumped into the system. Ironically, on the CPU cooler that pulls heat away better, would behave more like a space heater, because more of the energy makes it into the loop to be dissipated by the radiator.

Nope. A 500W computer is a 500W heater in your room. It doesn't matter how you cool it, heat dumped into the room will be the same. Which is why its a very good idea to fold in winter if you live in a cold place... for starters, you have a heater in your room and, secondly, you are working on something cool.

@swiftech crew: there is something I've wondered. Is there any chance of making kits such as the http://www.swiftech.com/mc800smccoolingkit.aspx reusable? I mean, do you sell the self-adhesive thermal tape that is required to stick those heatsinks? Are they removable?

The thing that always turned me down on watercooling was gpu-cooling... because it seemed insane to expend around $100 per card, and then not be able to re-use it ever. So, if this solves the issue, the world becomes much more itneresting thumb.gif

I'm sure it does. The competition just got a lot more stiff. It used to be, competition wise, Asetek or Coolit, what fans are included, price and warranty. Now the actual unit, the important parts, are the competition. Proper rad, proper pump, etc are much harder for the other CLC to actually compete, because they themselves can't change any of those things without high costs. They basically have to wait for asetek or coolit to improve their product. I'm sure they aren't exactly comfortable with that notion.

I have a pair of Noctus NF-P12 fans and yesterday I was going to test the low voltage adapter with a Swiftech 120mm PWM fan that I have but found that these adapters are 3-pin.

 

 

So how did he use this adapter?

 

I'd like some feedback from the Swiftech team on the question can the Swiftech PWM fan be controlled by voltage like Linus attemped to do?

You can use these adapters, but in speaking with Stephen, we don't recommend it. These fans are meant to work with 12 volts and then get adjusted via a PWM signal. Reducing these fans with voltage control is therefore not recommended because that isn't what they were designed for. This is also the reason why we include our 8 channel PWM splitter with this kit.

I'm the guy that mounted the H220 in the 600T and I do believe that I had to remove the rubber vibration dampeners to make the screws reach.

I scrounged through my junk box and found a fan controller cable that had a 4-pin connector with 3 pins connected.

 

I don't have a system running that I want to use to monitor the RPM but I did use a power supply 4-pin to do a visual test.

With the adapter the PWM fan barely runs so I'd guess 600RPM would be about right.

Without the adapter the PWM fan runs at full speed.

 

After 20 years of working around jet engines about the only sound that bothers me is the freight train that passes my apartment every night around midnight! biggrin.gif

 

So I'll run my H220 at full speed unless it sounds like that freight train. rolleyes.gif

Seems like y'all are being conservative with that recommendation. Isn't it six of one half-dozen of another if the fan voltage is reduced via PWM signal versus some other (fan controller) signal? The fan voltage is being reduced either way, no?

So you are saying, if I'm only pulling 130watts at idle from my PSU, its only pumping 130watts into the room? No matter how many cold block seatings I complete or how low I get that Delta T? That's great. biggrin.gif Now ya see why lunkheads like me need engineers. Dude you should gather the data for Tom and Linus, hahahaha.

I'll just pull my foot out of my mouth and get back to work.redface.gif

There is a difference as to where the energy is dissipated. Your statement is true 500w of energy would be created by the CPU, but not necessarily make its way into the room to heat at a 500w effect. If the energy is trapped in the box while more energy in the room is able to dissipate, you're talking less effective temperature change generated. This is of course assuming a larger view of the system, but the energy dissipated by the radiator will have a far larger effect on temperatures than the direct heat value generated by the CPU.

This is a strange discussion because its not really cut and paste temperature or energy, its a odd combination of both. It seems the OP we both replied to was either ill informed or carelessly chose his words while people who would correct him were reading.
