Noisy system The system is very noisy constantly whirring - can hear in next room, can I fix it?

There are so many possibilities... If you are SURE that the lamp is good (did you take it out & look at it?) Easiest: When you turn on the tv, do you hear a 'whirring' sound coming from the back? If you do, is it a 'smooth' sound or is it rough, scratch, & noisy?. If it is smooth, or if there is no sound, next place to check is the power supply. If it is rough & noisy, it is a bad color wheel. Unless you REALLY know what you are doing, anything other than a lamp replacement should be left to a professional repair person.

all washing machine are noisy it depend on brand but it is on all specially in small room or space

If its a loud "whirring" noise almost grindy...you need to replace that fan...it's about to fail. if it's a vibration type of noise, you should try tightening the screws first...if it's coming from processor fan, replace it before you fry your processor...

The fuel pump is supposed to run constantly when the engine is running. It is pumping fuel to the engine which is in constant need of fuel. It is starting when the ignition is turned on and then shuts down after a few seconds if you do not start the engine. This is exactly what it is supposed to do. You have no problem except for the pump being noisy. On a car that is 22 years old, I would suspect the fuel pump is failing and the noise you hear is it's death nil. Change the fuel filter and if the noise continues be prepared to have the pump replaced. It may fail suddenly or it may become hard to start. If you have never had it replaced just go ahead and do so, to prevent being stranded and a towing fee when it does fail.

About the only device in that heater that could cause the noise you describe is an electrically operated valve that controls water flow. Rheem is a better-than-average company so I would give them a call and describe your problem to them; I'll bet that they will be glad to tell you which part you need and supply it to you.
We had a heat pump system from Rheem that needed only the replacement of one large relay and the outside unit fan motor during more than 25 years of service and is still operating at age 30 in our former home.

Could very well be the fan. The motors can cause interference. There may be a solution to get rid of the noise. Some copper shielding tape may help. You could rule out it being a microphonic preamp tube by turning the amp on as normal and tapping the tubes with something non-conductive. If you hear the tapping noise coming thru the speakers while doing this to a particular tube, replace it. With power tubes, the tops of them turn white on the top when they become microphonic, along with plenty background noise.

bad throw out bearing,  You clutch is on the way out.

but no there was definitely a loud whirring noise in 5th gear sort of like a very noisy bearing. The bike still ran in 5th but it was definately becomming increasingly noisy. When I changed down to 4th the noise went away even if I slowed to the rev range I had been cruising in 5th. Same story with the other gears, but the noise returned with a vengence in 5th. Needless to say I rode the rest of the way home in avoiding 5th. Any ideas? I suppose I'm looking at a gearbox strip? Could the noise be anything else? ,Had a similar issue with my 1000S, only 5th gear was noisy - a sound like a dry bearing -other gears were silent. Bike had done 70,000kms and serviced correctly. Had Barry from IME check it out. Turned out to be both 5th gears needed replacing - looked like the case hardening on the gear faces was eroding and pitting. New gears went in and the box properly shimmed and happy to say 6000 kms later all still silent in the gearbox department. Plus the added benefit of slicker gear changes.,,,

This is normal.. It is keeping your computer cool when it gets too hot.

Many heating/cooling ducts are metal, so they conduct noise quite readily from the air-handling unit to your rooms. To break the conduction of sound, you can have a heating contractor insert flexible insulation ductwork between the heating/cooling system and the ductwork runs. If you hear a pinging or popping sound coming from the ductwork, this may be caused by thermal expansion or by air blowing past a loose flap of metal. Track along the duct runs, listening for the sound. If you find it, make a small dent in the sheet metal to provide a more rigid surface that?s less likely to move as it heats and cools.
