Fans failed to power up! Could it be a PSU problem?

I have checked with Asus Probe and it shows the same temp as the
Socket (35C). Motherboard monitor shows 53C on the diode. If memory
serves me right Probe doesnt show the diode temp. but the socket temp.

Assuming your ambient is about 21C I don't think your heatsink and
fans are earning their keep. You don't have the fans all pointing in
do you :-)

Radio Shack has a cheap digital thermometer that has a sensor on a
thin 3 ft wire. The sensor is supposed to be snaked outdoors but I
find it ideal to put at various places in a system to see how warm it
is when all the covers are in place (the probe is all-insulated) You
can always figure out some way to snake the wire out of the box.

Erm...no. The airflow is balanced. Airflow in to the case is from the
front and side fans @ 7V. The rear fan blows out @ 12V.

Cheers, I never thought that the temps I have are too high. As an
experiement, I might try reducing the number of fans and see what the
temps do.

If I wanted to build a quiet machine I'd start with the basics (a
quiet PSU and one case fan.) measure all the temps everywhere in the
case and add fans only as shown necessary. Also make sure your
overtemp and fan-failure alarms work.

My "hot button" is disk drive temps. For years I've been installing an
audible alarm next to the disks. It sounds off when the temp exceeds
110F, a conservative temp for disk drives.

Costs about $15. (no, I don't work for the company.)
