I have broken sunon maglev ventilator in acer aspire

Replace the inner part of the fan - some unit just slip right out.
check on kijiji and find a local computer repair guy that will sell you one for 5 or 10 bucks, or get a broken laptop for 50 to 100 and lots of parts. I had one broken wing and broke on off the other side to even it out... even though one side had 1 extra wing it wasn't that far off balance so vibration should be minimal.
if you keep your laptop clean inside around the heat-sink and fan area and put silver heatsink on the gpu and cpu as well as install the manufacturer drivers and update them to cool things down and speed things up and keep things from heating up.
One more issue is the charging port and charger end get frayed and or loose and will cause heating issues and have caused fires.
Replace batteries that are weak as they are continually charging too much.... Store batteries and at 70% and don't pull them out of the laptop while it's plugged in.
Fully charge batteries and fully discharge them between charges.
Good to have 2 batteries.
Don't use hot batteries especially after charging and don't charge a hot battery.

I am receiving intermittent 51:10 errors. Is this the CPU fan?

If it is actually throwing error 5.1:10 (which looks more like a bible verse to me) it is the CPU fan. On the one I have experience with, it was a standard appearing avid heatsink/fan combination, but the catch was that not just any 60mm fan will do. The original was 5000 rpm, which is PWMed down until the CPU actually does some work, then when the MB asked for full cooling, the 1st replacement I used (4200 rpm) produced the same error - it just wouldn't turn fast enough for the firmware/bios (or whatever was monitoring the 3rd wire pulse output from the fan). Moral: just replace it with an exact 5000 rpm fan (or in my case, I found a 6000 rpm fan that works just fine). HP really wants to sell you a $35 fan, or have some technician charge you for a service call just to replace a fan. BTW, I recommend a Sunon MagLev, outside of paying for a ceramic bearing fan ($$), it is the longest lasting reasonably priced (
Please correct the 51:10 to 5.1:10 if this hits the mark.

Where can I get a replacement cooling fan an NVidia Quadro4 750

I had a problem with the fan/heat sink assembly on an nVidia GeForce 5500 FX card a year ago. The card was in a multimedia computer and had lots of running hours on the fan, and the fan's sleeve bearings were shot, causing it to rattle. Failure of the fan seemed imminent, and before it did so and damaged the GPU chip on the card, I decided to fix it. Unfortunately, nVidia had used many different styles of fan/heat sink assemblies on this product, all of which were apparently obsolete. On closer inspection, however, one could see that the original fan on the chip cooler assembly was the core from a Sunon KD1204PFB1 12VDC/1.4W 40mm sleeve bearing brushless tubeaxial fan. One could also clearly see where the three struts were cut to remove the fan from its rectangular housing. The fan was glued to a clear plastic 3-tab mounting "spider", which, in turn, was attached to the heat sink with three small screws.

Here's what I did to fix mine; perhaps a similar approach will work for you.

1. Remove the video card from the computer.

2. Unplug the fan connector. On some cards the fan is plugged into a 2-pin header on the card, while on others it is connected to +12V via a Molex-type disk drive supply tap.

3. Remove three small flat head Phillips screws and lift fan assembly off heat sink. You will need a #0 Phillips driver or small jeweler-type crosspoint driver. DON'T LOSE THE SCREWS!

4. Very carefully pry fan from the clear plastic mounting spider. Most likely, it has been secured in the factory with some type of cyanoacrylate adhesive, i.e., "Crazy Glue". Take care not to crack the spider, as you will need to reuse it. It is better to peel the label off the back of the fan motor, than try to get the entire fan assembly off at once.

5. Clean up cyanoacrylate glue residue from spider by carefully grinding with an elliptical or spherical burr in a Dremel tool, to produce a flat surface.

6. Get a similar replacement fan. In this case we'll use a Sunon KDE1204PFVX 12VDC/1.9W 9.5CFM, 40x40x10mm MagLev bearing fan. (Ordered from Jameco Electronics, Belmont, California, about $7+tax & shipping. It costs about $2 more than the sleeve bearing OEM equivalent, but the MagLev bearings should outlast the computer by decades.) Cut the fan core out of the duct housing in a similar fashion to the original. Be careful not to snip the wires.

7. Align the fan motor cable with the cable guide tab on the spider, to route the cable away from the hub and keep it out of the fan blades.

8. Use a small blob of hot-melt glue to secure the fan onto the plastic spider. Press the fan gently against the spider until the glue solidifies, between your thumb and index finger.

9. Install the motor assembly on the heat sink with the three small screws. Route the motor cable between the heat sink fins as before. (The original cable had electrical tape wrapped around it where it passed between the fins, but I deemed it unnecessary to duplicate this. If the chip were to get too hot, it would probably cause the hot melt glue to fail, as well as cook the PC board anyway. In normal operation the heat sink fins stay close to room temperature.)

10. Connect the motor wires to the original connector, matching wire colors. (red = +12V, black = ground) If connecting to a Molex-type disk drive power tap, note that +12V is on the yellow wire.

11. Reinstall the card in the computer, connect the fan to the power supply, and power it up to verify that it spins. If everything looks good, button up the computer and you're done.

HP ZV6000 Fan Making Noise

I had a similar problem on my zv6000, but I've tracked it down to the fan in the middle (not the one above the CPU with the heatsink).

For anyone else that doesn't feel like taking your laptop apart twice (once to get the part number and twice to put the new fan in after you get it online, etc.), the fan is a Sunon Maglev GC 056015VH-A. HP doesn't carry them in the parts store anymore, but I ordered mine online from an independent retailer.
