Gateway DX420S has a case that can handle either 8X8cm or 10X10cm. Take a look at this part of the picture

If you want to be sure just take measurements from one screw hole to the next one.

I need to replace the small fan on back of gateway sx2801-01e, how do I get it out after removing side panel?


You're going to have to help me out here. I don't see it,

Scroll the page down to the bottom, and the photo that shows the Side Panel removed.

All I see is the Processor fan, and the fan for the Power Supply.
That is the metal case with the odd shape, at the bottom right of the computer view.

Rear view of Gateway SX2801 series of Desktop PC's,

If this is the fan that is not working, replace the Power Supply.

Inside that Power Supply are Capacitors.

A capacitor is designed to slowly build up a charge, then release it all at once.
There are cameras that use them for their flash units.

A crude example would be a large swimming pool, filled up by a garden hose; then one wall of the pool is taken down all at once.

Even after the Power Supply is unplugged from power, those 'Caps' can hold a charge for weeks, months, a lot of times over a Year.

If your fingers, accidentally touch the terminals on the bottom of a capacitor, the charge can be released to YOU!

If your fingers accidentally complete a circuit, that one, or more capacitors are in; the charge can be released to YOU!

Shock ranges from BAD to FATAL.

[The Input Stage uses Capacitors that can hold a charge, of Up To 100 Volts ]

How to remove fan from gateway dx4200

for replacing the fan you must open computer case unplug all power cords, remove 4 screws near the rear fan and pull out the power supply from the top interior. then you have at leat more 4 screws to remove the power supply cover out. then you will see the other 4 screws to remove the fan. if you just simply want to clean the fan open the computer case go to outside, take an air compressor and blow air into the fan and at the rear od the power supply on the air intake and you are done.

Rear grill computer case fan

The larger holes are for a 120mm fan. The smaller ones are for a 80mm fan. Personally I would get a 120mm fan.

I have an old gateway 7023ge computer and i wanted to find out the size of my cooling fans so i can replace them. i have 2 fans one front and one rear. they are both the same size.

Computer case fans for older computers were usually standard sizes of 80 millimeter or 92mm, maybe120mm. 25.4mm = 1 inch, so an 80mm fan is about 3 inches. Measure the diameter of the fan from the tip of one fan blade to the tip of the opposite fan blade. A 92mm fan is about 3 1/2 inches in diameter and a 120mm fan is about 4 3/4"

Again, these sizes are _nominal_, so whatever your measurement is closest to is what you need. You should be able to measure the rear fan from the outside back of the computer without taking anything apart.

I changed the CPU and Heatsink but it still overheats. What can be done?

What thermal compound did you use between the CPU and Heatsink ?

Get a higher air flow fan, or a whole new CPU cooler,
I would say any thermaltake cooler is better then any oem fan.

The rear case fan, you could get the same size, but a stronger fan.

If it was me, I would increase the hole size of the rear case fan
vent. This would allow for more air flow. But altering this could void a warranty , so this is only what I would do.

Gateway 831GM Eratic Fan Noise


This can be caused by several things:

1. Bad temp sensor
2. Bad voltage, but that will usually cause the whole system to restart
3. Too low maximum temp setting inside the chassis(setting is in bios), often denote as max case temp.

One way to bypass the problem is rig the fan to a molex adapter with a variable voltage molex to 2/3/4pin fan connector and adjust the speed to the maximum quiet setting.

The 831's did run a bit warm so if the case temp setting is set to low it will fluxuate quite a bit. Try adjusting the max case temp up around 50c just to see if that does it, if it does either use the variable voltage dial solution or add a second case fan that's always on, prefferably a low RPM running direct off molex so it will reduce the average temp and therby the need of the monitored case fan to rev up.

Auto restart

It may be overheating or the power supply may be failing.
