q:ts-670 replacement rear fan ?

[reiteravi]

one of the rear fans failed
as the original model was out of stock
replaced it by 92mm fan i already had
but it has different speed and cfm
so probably disturbing the air flow
can i make one fan push air and the other exhaust ?
or is it still more efficient to let them both exhaust ?
i feel like different speeds can cause turbulences
i ordered the original fan but don't know when it arrives

I recently upgraded the Fan in my TS-470 Pro to a Noctua NF-B9 PWM 92mm (4-wire) fan.

thanks
i also used this one but as ts-670 has 2 fans the different speeds probably makes ventilation less efficient
i see 5-7 deg. rise to about 50 for the cpu (upgraded to i7)
and 45 for the hdd even while idle

Not very helpful without the Fan information. Try this instead:

Code: Select all

#!/bin/sh
#
# Check System and HDD Temperatures
# 
echo "System Temperature: $(/sbin/getsysinfo systmp)"
echo "CPU Temperature:    $(/sbin/getsysinfo cputmp)"

echo "System FAN2 Speed:  $(/sbin/getsysinfo sysfan 2)"

Here is something to compare to:

Some of this output is ugly from mine, as my NAS only has 4 drives, and only 1 fan.
I'm still using the original i3 processor:

Code: Select all

cat /proc/cpuinfo | grep model\ name

sorry slipped through cut/paste
on startup:
fan 1 607 (noctua)
fan 2 1180 (original)

after a few min
fan 1 1080
fan2 2140

also tried manual tuning the fans
a little better but fans are on higher rpm all the time
which is overkill
i might find another noctua and try with 2 identical fans
the noctua are usually more efficient and almost silent

Comparing just RPM doesn't prove a lot to be honest. It is really more about CFM. (Cubic Feet per Minute).

Anyway, I'm not reading through multiple posts for this. You should have run the new script and provided the output. Seeing all the information in one place makes quoting it far easier as far as discussing it goes. I even re-wrote it for you to provide info from all 5 drives and both fans.

As long as the System and HDD temps are good you should be fine.

all this info is familiar and having modded my system i know the hardware limits
but having higher temperature than with stock fan is annoying
anyway thanks for your help , really
