Hi,

i changed the back fan of my box with a new, very silent one (Blacknoise Noiseblocker S2) (11-19db(A)).
When i run him directly on 12v, he's too loud for my ears, and when i put him on the mainboard 3pin (of the orignal fan) he's very silent.
Silent, but the xbox gets hot. up to 65 degrees (CPU) and 52 degrees (GPU) seems to hot for me, what would you say?

I read the FAQ which says 65 is the limit for the cpu and 49 for the gpu. dry.gif

Now i'm worried about the lifetime of my box.
If it's possible i don't want to install a second fan in the side.

Thanks for your replies,
regards,

Matthias

are those degrees in Celcius? If its in Fahrenheit thats Really Low. Try re mounting your heatsink, and Put some new Thermal paste on the bottom of both HSFs

hi, they are in Celcius of course.

I never disassembled the heatsinks, i only changed the back stock fan.

Greets,
Matthias

i hate this. now the box is really really silent... (i could sleep next to it) but its just a tick too hot for me.

Is there an idea except installing an additional fan or make this fan louder?

wow, i have had no problems, i bought a fan that has a 3 pin and plugs into my power supply
it plugs into the muther board so it can tell the fan what rpm to run at and then plugged the power into my 12v supply and when i put my hand on my xbox its always cool even after 14 hours of xbox live gameing.
and its quit.
plus i put a fan under my hard drive.
but tho i have the oldest xbox, one of the originals, and i have noticed sutile differences between the old version and new versions
i also have a fan on my heat sink to lol

couldnt you just use xbtool to increase the fans speed using the stock 3pin

hi, i measured the voltage at the stock 3pin, which is 12V.
I guess they built in some resistors so the fan doesn't get the maximum power.

So xbtool woudln't do anything...

Are you sure its not blowing air in, instead of sucking it out. Just a thought, I'm not trying to be an ass or any thing.

yeah i'm sure... as i said, the fan is pretty quiet as i'm running it at 1500rpm (11db(A)).
if i turn the pot up (when i'm having it on the 12v of the harddisk) the fan gets "loud" (to me wink.gif) but keeps the box cool.

Yes, XBtool would do something. Modify your BIOS to run at a higher speed (default is 20%) and you'll get more power to the on-board (motherboard) fan connector, therefore making your fan run faster. How did you think those software hacks sped up the stock fan? The same changes will affect your mod fan too.

check the blade angles, the newer ones might just not be moving enough air...

You sure the fan's blowing air the right direction?
