This was an example only.

About worrying about heat on cables, so long as they are insulated I wouldn't worry a lot. You could run them through the split tubing for extra protection.

I have this thing about heat, it makes me very nervous. All the wires run down the middle of the car with heavy carpeting, and seats that sit on top. So seeing them is no problem. Im not worried about the DVI because its so think, its just the audio (the special 7.1 cable for my Xtremegamer sound card, its very thin) and the USB. Maybe I can simply place a heat absorbing pad in the areas that get warm.

I have a fiber optic cable running under my seat from my Alpine sound processor to the head unit and it's very delicate and never had any problems.
If your really worried about the heat you can get some thermal pad material and pull up carpet and put it in between your cable and carpet. I'm not sure what's it called but I know its available. You'll see in car around the firewall and where the exhaust runs.

Hahahaha i'm really not use to not being able to run the car on battery for long time lol. Once i powered the amp that ship sailed. I just killed my battery in like 30 mins or so. Maybe it wasn't fully charged to begin with. Anyway. I cleaned up my wire mess to the best of my ability. Everything but sub amp is installed so i have no bass but everything else is working well.

My thermal issue just got a lot worse. Even on a cool day with no sun my comp was at 55C. This is going to cause a problem i know it. Will just have to wait and see.

What are you using to pull the temp? Are you doing it from BIOS or Windows?

**Bxsteez** · 06-12-2009, 12:38 AM

windows. I use coretemp program.

Are your AMPs mounted close to your CarPC case, if so that could generate a lot of heat.

I never trust the temp reading on the PC itself, especially in a car environment. I used Speed Fan and it kept saying that my GPU and PSU were on fire. Thing is my case is designed to move $h!+ loads of air over the PC. Even if its hot in the cabin, as soon as the PC fans come on, its already started to drop tempatures by a huge amount. I then decided to buy a laser thermometer, that seems to be acurate. You can also touch the heatsinks with your finger. Let me ask, are you using the original thermal paste on all the heatsinks? I would buy a high grade thermal paste and replace all the old paste. I know on the GPU it had thermal tape, even though it has little hold tabs that keep it in place. I then scrapped all of it off and put thermal paste on it. That helped alot.

I agree..... If they are close you may have to design a case that can move alot of the air away..... On the rear PC systems, they are all stacked up with the AMPS sitting under them. I am going to mount a fan that blows air in from the top, then another fan that blows the air out the bottom side.

Coretemp seems to be pretty accurate based on the bios reading as well. I did a comparison when i first installed the app. My Amp is quiet close to the computer and i agree that is causing some more heat but DAMN 15 degrees. Thats a huge amount of additional heat. I think its the small compartment its in just not having enough air flow. What i need to do is cut some holes in that false wall and install some fans or something. I'm gonna wait for it to fail before i try and do that though. The datasheet for the processor claims it will work fine from 0-100C and if i stay under 70C it may never fail. We shall see. Its going to be 88F next friday. I'll wait for that and see how bad it looks.

I think i'm just take my drill to that MCS case which is apparently poorly designed. I'm gonna have to just drill some giant holes on the top and hope that helps the issue. I may even get what i believe to be a better cpu cooler.

Gotta wait till it fails first though

You know I always have these crazy ideas, but why not cut like air slots in the part behind the seats next to the rear windsheild. like next to the rear speakers. Maybe one on the side of each speaker. Then mount fans that draw air into the PC/AMP compartment, then in the false wall, cut 2 holes also with fans pull the air out into the trunk.

PS: Im fixing my heat issues with heat shield tape for the wires.
