Sounds cool Brandon, I'd love to snag one if theres any left.

Side note: I wonder how well a Hyper 212 Evo will cool a CIM motor... (Or the new access point we use this year, that thing gets hotter than I thought it would...)

Re: New to FRC- You guys are all amazing!
 

I have a couple laying around. Should I test :]

Re: New to FRC- You guys are all amazing!
 

Sure, why not! Obviously it wouldn't be practical, but I could see teams needing to cool down the motors between matches during semifinals and finals. :P

Re: New to FRC- You guys are all amazing!
 

Alright. Ill have it done this weekend.

Re: New to FRC- You guys are all amazing!
 

I don't know if it would work that well. The 212 Evo works best against a flat surface.

Re: New to FRC- You guys are all amazing!
 

The surface area would be decent on a CIM. Applying the right amount of thermal compound is the issue. Can't wait until you guys manufacture the CIM waterblock.

Re: New to FRC- You guys are all amazing!
 

The back of the CIM motor is (mostly) flat, however most of the heat isn't dissipated from that location, but it does get hot after a lot of continuous use. Some thermal paste will definitely help instead of direct contact.

Anecdotal story: Last year the students were doing a demo, for several hours. Eventually the performance of the robot was quite abysmal. I noticed the motors were hot...REALLY hot. I took some damp paper towels and wrapped them around the motor...you could hear the water sizzle and evaporate off. So maybe CoolerMaster could make a water cooling block for CIM motors! :rolleyes:

Edit: I see that Samuel had the same idea as me, and we posted at the same time. :P

You got sniped

Re: New to FRC- You guys are all amazing!
 

Well let's think about this. The motor gets hot and it needs a way of dissipating the heat. I can think of 2 ways I would try to go about this based on skill, time, space, etc.

1- Take a heat-sink similar to this and drill out the middle. Slide it on the motor. The fins will carry heat away. Not the greatest, but it will help. http://www.coolermaster.com/cooling/.../x-dream-p115/

2- Take a liquid cooling system (closed loop) and disconnect the part that goes against the processor. Swap it out for a hallow cylindrical sleeve that fits around the motor. This would definitely take some effort and custom parts but it sounds like it might be worth it if it can be used every year.

Keep in mind I have never built a robot and have no idea what I'm talking about :P

Re: New to FRC- You guys are all amazing!
 

Actually, your first idea kind of exists: http://www.andymark.com/product-p/am-2865.htm

If you can blow a fan over them, they are more effective.

As for your 2nd idea, maybe all teams should bring their gaming PCs with a custom water loop, and put it in the pits and cool the motors down between matches! :P

Re: New to FRC- You guys are all amazing!
 

Well, you don't need a PC to run a water loop.

No you do not. Really all you need is a power source for the pump and fans. Which run over pwm/3pin something the robo Rio has. Water cooling robots is totally overkill but I custom loop would look sick. If anyone wants to sctuslly do this contact me and ill give you a good price on parts. Also if anyone needs a bitfenix prodigy m ill give it to you for free plus s&h I need to get rid of it.

Re: New to FRC- You guys are all amazing!
 

Is anyone using Cooler Master products this year with their team? I'd love to hear about it and how it has worked out for you.

We have 212 evos in all of our pcs.

Re: New to FRC- You guys are all amazing!
 

My personal pc, often used by my team for cad, was made using a CM case and uses a 212 to cool the cpu.
Has cm considered attending the world championship? You'd be able to meet teams from every corner of FRC there and be able to learn quite a lot about the ethos of FIRST.
