Aiyah! Any hp charger will so long as got USB power lah as notebook cooling fan is powered by USB. Do make sure u buy the right hp/charger withe the correct plug to fit ur avr ac outlet socket.

Dunno whether PCR made or not (although I'm fond of buying AP stuff ) just used an old h/p charger I had laying around in the storeroom. Has been taikor-la now the title should go to 907 (got ar?) Luckily not much news bout the 7 series (stopped goin to Audioholic) or else need to scratch the upgrade itch

M thinkin of buying 1 of those mini table fan (made in PRC) but like I said been using onkyo for long hours so far no problem xcept for the small incident.

Added on June 5, 2009, 1:31 pmNot the set-up tripped, the whole house black-out!!! After some investigation only found out it was the DIY fan. Dunno why but all wires were properly terminated and used heatshrink to protect (learned fr speaker wires DIY ) Probably like what Horny said 'PRC made charger'

solly ah...dun quite catch what u say. yesterday was in carrefour under the computer section, a lot of fans but all plug into USB. my onkyo 606 no have usb port nor any AC outlet. my pionner dvd player got one USB port, will that do or will the fan run if plug in. so not sure why still need hp charger. a bit confused here....

Aiyoh! Hp charger with USB is to be use to powered up the note book cooling fan although it is originally intended to be use for charging hp. Onkyo 606 no powered outlet? Then use use normal power socket. Just switch on the fan when u use Onkyo 606.
I do hope u get what I meant.........my English very very poor pri 6 level only!

if can, should just install aircon in room. placing a fan on top of your avr will generate a lot more dust inside.

Bro,

The fan is suppose to 'pull' hot air fr the AVR not blow into the AVR hence dusting is minimal

With fan on top air is pulled out from the top, but new air also comes in from the side right?

Whether push or pull, with a fan there is more air circulation and wouldn't that bring more dust in?

I just put notebook cooler big fan on top, switch on only after 3 or 4 hours running my Onkyo 905. Find a very low noise fan, no need fast fan. Normally my AVR running at whole night without fan.

I put a 1000rpm fan on my AVR...
very low noise at 17db.....

How do u guys power the fan? Normally those PC fans need like 5V or 12V supply right?

I power the notebook cooler fan using my Onkyo 905 AVR USB port.
One simple solution if your Onkyo AVR don't have USB port, just buy USB hub with power adapter. Connect the USB power fan to USB hub.

How much is TX-SR507?

Bingo! Finally got the answer..... so the usb port can be used to power a 12v fan Off to Digital mall to buy a usd fan

bought a fan which just plug into AC outlet. its reasonably quite. cannot hear watching exciting movie

want to ask, why am getting a lot of mini electrical shock fm the AV and also my DVD player when touch. my wife also got it once a while. it goes to the extend of holding the microhone sometimes. is my power outlet to near or any way to prevent such shock.

DC leakage from power block to metal chassis.. that 1 normal lo..

your earth missing

Anybody know why so many equipment don't use the earth nowadays? Many of them have the IEC socket but only use 2 pins instead of 3 pins. Why don't they also use the 3rd earth pin?

Can please share how to earth it.... appreciate if there are various option.

The reasons so many electronics don't have earthing is because the are not needed anymore. Why? Because most electronics comes with plastic body which doesn't conduct electricity therefore cutting out the needs for earthing.

However if the body of the electronics is metal, it is best to have earthing.

here's wat i do super easy, buy a coolermaster12cm fan Rm,40, an ac/dc multiadapter RM9, cut the cord of the multiadapter, and cut the 3pin to 4pin adapter included from the fan, and connect it to the multiadapter cord, (according to polarity of course, its rather save, max output of the adapter is less than 12v) and viola, changable 3pin cord for any 3pin pc fan,
btw i set to max output on the multiadapter, since is cheapo brand, its output is less than 12v ,run the fan just nice, i even modded a switch to turn on and off,
