Full tower case with TEC A/C + HQ Filters

Recommended Posts

I would like to see a full tower case that has a TEC air cooling setup much like the Nextherm. I recommend building this case with a dust-free approach. To do this, use K&N automotive lifetime air filters on all intake fans and ensure that there is a slight positive pressure in the case (account for the PSU fan as well). Make the filters easily accessable without the need to open the case so that the filters can be removed and cleaned while the PC is still running. To really go all out, you could make miniature air conditioning ducts made from a flexible plastic material or durable hard plastic. The ducts would blow on the motherboard, hard drives, and the 5.25" bays.

Another issue with the Nextherm case is that it uses a lot of wattage even when the TECs aren't running. This system would need to be build with *some* energy savings in mind. When the TECS are disengaged, only the fans should be drawing power as well as the control console. This case I imagine would be priced for the hard-core enthusiast who hates dust and wants something better than an air cooled case. The main tecs would work very similar to the Nextherm as they would have an air intake on the front of the case and blow the hot air from the hit side of the TECs out beneath the case.

This case would have all the great features of most of the better cases out there. At least 4x 3.5" internal bays for hard drives, 3 5.25" bays, and 2 external/internal (optional) 3.5" bays for FDDs or hard drives. Also I like the idea of the rail system for the hard drives where they are mounted sideways on rails. I would recommend this for your 3.5" internal bays.

How feasible is it for you to build such a case? I can imagine there would be huge demand from enthusiasts who would be willing to pay for something that actually can lower temps below the ambient temperature even if the electric usage is $84/year more to run such a setup. You could also make the air conditioner automatic using a control panel to auto engage the device when the CPU/inside case temp goes above a user-defined/set level. I am thinking a case such as this would sell for around $250-$299.

Problem of peltiers/TECs is their bad efficiency, they draw much more power than they can transfer heat so removing bigger amount of heat from intake air would actually rise room temperature...

which is rather counterproductive.

Ducts can work well in point cooling but trying to cool every component with them would be "gas factory" approach. Controlling airflow and intake routes and placing components along them is more practical.

I do agree that TECs generate more heat for the amount of cooling power you get. This is why such a setup will need to have a fan that routes the hot side of the pelts directly outside the case. If you look out how Sytrin's Nextherm case is designed, the hot side of the pelt has a fan that blows the hot air through a vent below the case. It is possible to do such a setup...When the case was reviewed, in some cases there was about a 4 degree (F) drop in temperatures which I think warrants some attention. If coolermaster could use more powerful TECs in their setup they could possibly achieve 10 degree or more temperature differences between having the pelt on and off.
