Engine Heatsink When i turn on my computer it makes a loud engine sound? Please help me!?
Ok when i turn on my computer the computer will not make any noise for about 5-10mins or unless i start up a application for instance(Internet, or World of Warcraft).Then it starts to make this loud engine noise and you can hear it anywhere in the house!please i need help to fix this problem! i know its coming from the fan.
System Details:
-I have a Compaq Presario PC-SR5010NX
-Intel(R) Celeron(R) D CPU 3.46GHz 3.47 GHz
-1527 MB Ram
-32-bit Operating system
-Vista (Home Basic)
I hear from some people that u can Remove the fan (just the fan - leave the heatsink in place)
Remove the sticker from the centre underneath
Drop some oil in the hole
Put the sticker back on
Re-attach the fan and the porblem should be fix. Can it? Or is there other way.
Crystal has it;
here's some extra info
the noise is caused either by dust causing the fan to be out of balance
which is usually the case with a newer system
or
in an older system the fan is usually baked and will still make noise even when cleaned out, and needs to be replaced,
(occasionally, but rarely it's something is touching the fan and it's only noticeable when the fan speed is high)
the fan and heatsink are usually sold as a unit
though occasionally you can find a fan that's nearly identical and can just replace it,
best rule for replacing the fan alone, is to find one with the same or higher rating, if it's lower, it will run on high more than it needs to and will burn out sooner, and can put the CPU at risk during high load
If you are in need of an enclosure for your electronics and debating the pro's and con's of what to do, then here are some points for you to consider based on the latest machining techniques that may provide you with a better solution for no extra cost.
What do you do when you need something more than a customised off the shelf enclosure?
Have you considered a bespoke enclosure manufactured to your exact requirements?
Do you know that Casting and Moulding are not the only options for a bespoke enclosure?
Have you considered utilising the latest machining techniques to manufacture an enclosure for your electronics?
Why should you choose CNC machining for your electronics enclosure? The latest CAD CAM systems and machining technologies have revolutionised what can be achieved cost effectively by the machining process and this has allowed companies to reap the benefits of the process at a cost that many would have thought impossible only a few years ago. Here are some of the advantages of the process.
Unique and Stylish Design Modern machines can produce any shape even 3-Dimensional forms quickly and easily, so no longer do machined parts need to be angular and simplistic. Complex shapes can now be machined as cheaply as very simple profiles.
Reduced Capital Expenditure Casting and moulding techniques require expensive up front tooling. The machining process requires a much lower initial set up cost.
Design Flexibility When using the machining process for your components there is a negligible cost implication when making design changes as your product matures. Even significant changes at the design and prototyping stage can usually be accommodated with minimal cost or lead time.
Thermal Performance A machined enclosure can satisfy all your thermal requirements. Complex heatsinking and cooling features can be designed in with the minimum of thermal interfaces.
EMC Performance Particularly if an enclosure is machined from solid the enclosure will have excellent EMC performance simply by reducing the number of interfaces. Depending on your requirements a variety of concepts can be used from simple metal to metal contact to a sophisticated tongue and groove solution which takes advantage of the accuracy which can be achieved by the machining process even on very complex profiles.
Environmental Integrity If a component is machined in one piece it significantly reduces the potential for leakage and sealing features such as o ring grooves can be accurately added.
No Additional Processes Unlike the casting process machined components are completed in one hit. There are no expensive extra processes required to ensure accuracy or sealing integrity.
Accuracy The Machining process can easily and without any additional cost achieve accuracy of important features which could never be achieved by casting or moulding. Typically an overall tolerance of +/- 0.2mm can be achieved with ease over the entire volume of the part
And finally some myths expelled
"Machining from solid is very wasteful of material" Machining a box from solid does require significant material to be cut from a single block, however the difference between this and machining individual panels is usually less than you would first imagine. Also the cut material is recycled so nothing is actually wasted.
"Material Removal is slow and costly" Using modern machines and tooling machining of aluminium and plastics can take place at previously unimaginable speed. This is just one of the advances which has made this into a viable process for production enclosures.
"Programming the machines is very time consuming so only viable for large volumes" CAD CAM has revolutionised this process. The same 3D models used in the design process are used to create the tool paths for the machine. There is no time consuming manual programming of machines followed by a slow step by step proving of the program. Tool paths are created off line, simulated on the computer and then electronically downloaded to the machine.
