5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
I'd like to add a cooling fan (CPU type) to my aftermarket navigation unit. I'm thinking I could tap into the ignition triggered positive cable as well as the negative cable that go into my stereo. I'm not great with calculating electrical loads, etc. Does anyone know of an easy to do this? I'm trying to get it so that the fan turns on/off with the unit....
x2... and will you be able to control it? In the summer, yes I know my unit gets very hot.. But during the cold winter, it takes a while for it to warm up.
Maybe figure out a way to tie it into the HVAC system, since the vents are right there..
..if it is not broken, don't mess with it. So, does the unit shut off when overheating or what? If so, send it back to the mfg as units should be designed to work w/o an extra fan.

Electronic works OK in cold weather. But heat can melt things.
The best way for this is see if the receiver have a power antenna connector. The one that when you turn on the receiver it extend the antenna. I'm not sure if this connector turn off the power once the antenna is fully extend.
The unit works fine so far, but if you look at every brand name manufacturer of head units out there (i.e. Pioneer, JVC, etc) they all come with a built in fan. Its just a known fact that cooled processors work longer and more efficiently than overheated ones. I'd like to do this if its an easy fix. TTM77- thanks for the great idea. I'll have to check that cable out....

A CPU may become unstable if it's too hot or if you give it insufficient voltage. If you give too much voltage then it will overheat and also may fry depending on the amount of voltage.
HOWEVER, if a CPU is within operating temperature (let's suppose between -20 and +70 Celsius degrees) then it will work EXACTLY the same at ANY of the temperatures in that range. It will not work any more or any less efficiently.
I just thought I'd throw that in so that people don't have misconceptions. However, keeping the CPU cooler WILL extend its overall lifespan.
If you cannot attach a computer fan somewhere, consider installing a small chipset or video card RAM heatsink on the CPU and/or chipset of your device inside. Use either Arctic Silver 5 or Arctic Cooling MX-2 thermal compound to bond the thing. Use about 1/4 of a pea size drop or even less. The RAM heatsinks usually come pre-applied with 3M thermal tape.
Even without a fan, a passive chipset heatsink will dissipate heat better due to the increased surface area over which to spread the heat out.
You can find all of these parts at NCIX (they have a US and Canadian site) or Newegg (they have a US and Canadian site).
If you require any assistance please feel free to ask me. I am an expert in computer hardware.

...let me guess, you bought a "cheap" unit from a discount store like e-bay, found "made in China" on it and now think it's not designed right as it gets pretty hot...? Bogus. Go to your TV and touch some of the components their. Btw, their are different grades of electronic chips/components re allowable temp range. Commercial applications have 140C ratings (normally), lower grade is 120C, military grades are higher etc...70C is just the max spec on the operating temp but not the max spec on the actual component surface temp.
Again, if not broken don't touch it and in particular if you are not an expert. Attaching a heatsink like described to your unit is complicated as you need to take the unit apart and put the heatsink directly on the chip you think is in most danger...do you know wich it is? Also voids your warranty...
