PC fan noise... Are you drowning too?

I am interested in hearing about other peoples fan noise experiences.

Recently, I purchased one of those brand new Dell Dimension XPS boxes with all the bells and whistles (3GHz processor, Radeon 9800Pro card etc.)

Performance - no complaints. The noise required to cool such performace? Mind numbing! The 5 cooling fans in this box, which is designed for home / office use, can only be compaired to sitting next to a raised floor server rack, or more plainly, an upright vacuume cleaner or hair dryer. It is quite apparent I will NEVER get "accustomed" to this constant noise floor, and my productivity has plummeted since purchasing this box. If noise is the penalty for performance, I'm beginning to wonder if my ol' Pentium 3 wasn't such a bad box after all.

I could understand having such noise while blowing through Grand Thief Auto Vice City or something like that, due to the processing power required. But the unbelievable noise also exists while sitting there trying to concentrate on wording of a business proposal in a word processor, or writing HTML code. How could the processor POSSIBLY need that much cooling to place letters on the screen and move the mouse cursor around! To get an idea of what I mean, turn the vacuum cleaner on, place it next to your desk, and watch your concentration flatline right before your eyes.

I can't be the only one in such a situation. Dell's discussion boards are FILLED with such complaints. Is this one of the new issues computer users will have face in the future?

Does it really need 5 fans to keep the box running at a reasonable temperature?
I suspect that at least 2 of those fans are unnecessary and were just added to impress people who would be impressed by such things.

My computer, which was pretty top of the line in February has three fans: The CPU fan, the video card fan, and the fan in the power supply (was an expensive "silent" one).
It runs so quietly that I have sometimes forgotten to turn it off because I thought it was already off. (With my old computer, I would listen to the fan noise to see whether it was on when I left my apartment.)

Captaffy, no professional PC builder puts fans in to impress anybody. If they are there the chances are that there's a good reason. This is a constant problem PC manufacturers have i.e. well meaning amateurs thinking they know enough to alter their PCs. They remove fans, burn out vital components and then blame the manufacturer for the fault.

Users add the odd PCI card themselves but do you know that professional PC companies put a lot of thought and planning into a model, including planning for airflow and optimising the PC to achieve a balance between fans pumping air out and not allowing the PC to overheat? Just because a PC put together by the local village idiot is still working you cannot compare that PC with a professional system built by people who know their stuff and who've worked out and planned everything from the calculation of total wattage of juice required from the PSU to the cubic feet of air that needs to be pumped through the PC (for a given room temperature).

Remove fans at your own peril. Oh yes, and try to avoid that capacitor when you are modding your PSU, it could kill you even with the power plug disconnected <sigh>.

I can't say I share your optimism there.

In this case I would be said village idiot, and said village idiot's PC has been running without heat issues for almost eight months now.
Honestly, what do you think these "professionals" are doing? These companies that create gaming PC's exist soley because there are people who are too scared to put their own PC's together, or because people don't have time to put their own PC's together.

There are thousands of computers out there built by gamers that don't have 5-6 fans, and that are running just fine.

who've worked out and planned everything from the calculation of total wattage of juice required from the PSU to the cubic feet of air that needs to be pumped through the PC (for a given room temperature).

That would certainly impress the friends of those computer owners.

Manufacturers do not always know best.

There was once a very expensive machine set up at an agricultural college which kept dying from the heat.

The vendor was a friend who I owed many favours to.

After looking at the machine, I removed all but one of the five original fans, applied magic duct tape to the right places.

No more deaths from heat.

Speaking of quieter fans, I will be trying out 80mm case fans from Silenx. About 14db per fan, compared to the 35db ones from Antec currently installed in my system.

A professional PC builder knows a darn sight more than the average "casual" assembler as evidenced by the large volumes of blunders, screw-ups and death defying risks we see in PCs that users/amateurs have done some work on themselves.

That does not make him the village genius :-) The fact that a particular PC is not crashing from overheating does not mean that it is optimised for performance or stability, does not suggest that the components are running within rated temperatures, does not do anything to indicate that the assembler of the PC had any more than the basic knowledge of using a screwdriver ...and some luck.

There are thousands of computers out there built by gamers that don't have 5-6 fans, and that are running just fine

Again, because a PC appears to be running fine, that is not necessarily the case. It could be destined for a short life from components running just a wee bit out of "recommended" temperatures. Also, there are several low-end PCs out there that just don't generate enough heat to warranty half a dozen fans.

Some of the keen games display a tremendous range of knowledge on PCs, components and optimisation. They'll list off for you the full range of Pabst and Zalman products complete with part numbers and prices. Many full-time "PC assemblers" wouldn't know a RAS latency from a CAS latency. So the fact that something is built by a gamer is neither here nor there.

That would certainly impress the friends of those computer owners

The idea is not to impress anybody. One reason why manufacturers of performance and high end PCs have expertise in areas like this is because they are interested in the topic and it relates closely to what they do. They HAVE to know it. Another reason is that they are scrutinised more by the providers of the (legally required) public liability insurance. Joe Bloggs working from his garden shed won't pay if the PC he built you catches fire and burns your house down while you are away on hoiday. "Proper" manufacturers are regularly checked by public liability insurance providers on measures taken to ensure the safety of the public (customers).

My general advice still remains, burn a component out and it probably won't be replaced under warranty, when in doubt go for more fans & a cooler PC rather than less noise, if you want quiet - get an expert's advice and if you don't have one handy then do some research on the net. And please, please, don't open a Power Supply to make any mods.
