What is the noise level of the CPU fan? Could it run also on 5V?
The fan is actually very quiet. There is more noise coming from 2x 1TB WD HDD attached to GPS+.
I tested few fans and some can run on 5V, but the one I finally used does not. It starts spining at 7-8V.
So this is the reason for adding Traco power boost switcher.
a sink of this size should be capable to transport the 10W of the plug by convection and not require a fan. Would you mind trying?
I absolutely agree with you. This heatsink is a hugh overkill. Nevertheless, while CPU stressing the GPS+,
the heatsink does get warm without the fan being turned on. I estimate the temperature to be
cca. 40-45 degrees Celsius. With the fan turned on, the heat sink is pretty cold. Nearly as cold
as a beer should be. ;-) ( The switch mounted on the case is used to turn on/off the fan.)
I had a huge overheating problems before, so I want to be double sure that this problem is solved for good.
I posted the pictures taken with thermovision camera before, where we can clearly see that before
modifying the GPS+, the inside temperature was well above 90 degrees Celsius!*!??!
Looks good, does the entire thing fit inside the case incl the sink?
How much did the heatsink cost? Can you post pics of your completed setup
The modifed version doesn't fit inside the case. I just kept the lower part of the case
and put the electronics there.
I picked the heatsink and fan from an old PC motherboard, so I can't tell you the price.
I will attach some pics of my final setup tomorrow.
You say it runs perfect now, does that mean 2x Gbit and wlan on ?
Unfortunatelly, I don't have an option to test Gbit network. GPS+ is connected to my
trusted Asus 500g Premium Wlan router via 100Mbit Ethernet. I also don't use Wifi
on GPS+, as this is a task for the Asus as well with added directional antenna.
In the near future, I plan to switch to Gbit and Wifi N router, but it won't happen
in a week.
When I said that GPS+ is running perfectly, I actually meant that it doesn't reboot
and heat up anymore of course. GPS+ is used as HTTP, FTP, SSH and Samba server,
torrent client and NAS with 2x 1TB HDD.
