Fan compatible with HP Elite 7000

Processor fan? Computer case fan? Palm fan, lol?

1) Computer Case Fan = System Fan:

The computer case fan is referred to as the System Fan, in proper geek speak.
Back of the computer case/bottom for the Elite 7000 series.

To remove;
1) Unplug the computer from power,
2) FOLLOW Anti-Static Precautions,

3) Remove the four Philips head screws, from the back side of the computer holding the fan,
4) Unplug the fan's cable from the motherboard connector.
Red/Brown connector on motherboard labeled SYS_FAN1

This is the HP Parts Store, and listing for parts for your computer,

Scroll the page down to a little less than halfway.
Fan [Electronic Parts]
You can click on the camera icon to the right of -> In stock, to view it.


Yeah RiGhT, HP!

Let's look at another example from an aftermarket dealer,,Computer,Part,449207001.aspx

Yeah, right!

If the computer case fan is the problem, I need you to measure it.
Laying flat, measure both directions across it.
Now measure the thickness.

Let's look at some examples of computer case fans,

Need a Millimeter to Inches converter?

Click in the mm box, then type the size. Now go below, and click on Convert.

Let's use 120mm computer case fans for an example,

Hmmmm, around $6 to $15 bucks. !O_O!

Just one website, just the 120mm examples. Post in a Comment as to the outside dimensions, and I'll post a few websites for you.
(70 bucks, lol!)

We're talking about a Processor fan?
I do not see a listing. Probably part of a combo, and is listed three listings under the -> Fan [Electronic Parts]

-> Heat Sink [Electronic Parts]
586374-001 -> Contact HP

Contact HP? Ummm, no thanks. I'll just look that up with aftermarket dealers.,Computer,Part,586374001.aspx

$100 bucks. Ummmm, No.
That babies going to get dust on it, sitting on your shelves.

Yep. Seems to be the norm.
Nope, not this kid.

When purchasing a Processor fan, you can purchase the Fan by itself, if you know the dimensions, and method of mounting, or you can purchase a Fan/Heatsink combo.

If the Processor fan is bad, we need to talk maryscopes.

In-between the Top of the Processor, and bottom of the finned Heatsink that sits on it, is Thermal Paste.

A magnified view of the Top of the Processor, and Bottom of the Heatsink, would detail, 'Hills, Valleys, and Pitholes'.

When you mate the two parts together, Heatsink to Processor, there are Air Pockets created by these imperfections.

Air is an Insulator, not a Conductor.
Thermal Paste fills these voids, or imperfections, and is an Excellent conductor of heat.

IF the Processor fan quit spinning, or has slowed down, or spins intermittently, the Processor has overheated.

The heat may have caused the Thermal Paste to dry up, or harden.
This -> Greatly, reduces the thermal conductivity of the Thermal Paste.

In fact, it will become an Insulator, and not a Conductor. (Of heat)
It is best to replace the Thermal Paste.

Even if you just replace the Fan.
(When you replace a Fan/Heatsink combo, it is a required thing to replace the Thermal Paste also.

We'll come back to this.

The easiest things to do, of course, is to replace the fan itself.

The HP Elite 7000 NV525UT comes with an Intel Core i5 processor,

Yours may be different model number, but I suspect it will be an
Intel Core i processor, however. Plus an Intel Core i5 processor.
All you have stated is HP Elite 7000.
That is a Model -> series.

There is a Model Number also.
For HP the Product Number is the model number.
P/N = Product Number.
This on the back, or up on the side, in a white Service Tag.

There are two processor sockets used for an Intel Core i5 processor.
The older LGA 1156, and the newer LGA 1155.
(Looks backwards, huh?)

Good thing is, the method for mounting the Heatsink to the motherboard, is the same for both, the LGA 1156, and the LGA 1155 processor socket.

This is because the two processor sockets use the same dimensions,

LGA 1156,

You can click on the photo to enlarge it. Same thing for the next link,
LGA 1155,

You may be thinking by now, "Man, I just want to buy a fan. Why all this 'rhetoric'?"

Have to get the correct one, or it will not fit. I do not have your HP computer in front of me, and need your eyes so we together, can find the correct one.

I now want to show you a couple of basic examples, using Fan/Heatsink combos. One for the 1155, one for the 1156 processor socket.
This way you can look at the fans on top, and see the method they use of mounting,


See the four Philips head screws?
The one to the left is pretty easy to see. There is one on the opposite corner. One at the top right, and one opposite of it.


Same method of mounting.

May be cheaper, and easier, to just buy the fan/heatsink combo, remove the fan, and use it.

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

Relieve your body of Static BEFORE, reaching inside that unplugged from power, computer.

Computer on a table, computer unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal frame of the open computer case.
This action will relieve your body of Static.

IF you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

Replacing Thermal Paste:
I will detail this out in a following Comment.

Koliki je broj obrtaja RPM ventilatora A38001-001; kakve lezajeve ima; kako se odrzava (cime se podmazuje) i koliki mu je ukupan vek eksploatacije u casovima rada hours? Thank You for Your`s Assistance,...

No, that fan is cookin'! > Spinning too fast.

The Sanyo A38001-001 from Intel, is only designed to spin in those RPM's when the Processor is REALLY Hot!

Usual RPM's are around 1750 to 1850.

A) Did you just buy and install this Heatsink/Fan combo?

1) If so, did you thoroughly clean the top of the Processor's case?
Used a scraping implement like a plastic credit card to scrape off the old Thermal Paste, and then used Q-tips dipped in Isopropy Alcohol?

[ Also know as Rubbing alcohol. 91% is best, but 70% will do in a pinch. Make sure it's dry afterward though. {91 percent alcohol, 9 percent Water, or 70 percent alcohol and 30 percent Water)

The Q-tips dipped in alcohol will wipe up the gooey mess of thermal paste. Usually takes quite a few Q-tips.

Isopropyl Alcohol is EXTREMELY FLAMMABLE!

Use in a well ventilated area with No sparks or flames present.

2) You did apply Thermal Paste, and correctly?
One small drop about the size of a large pea, in the middle of the top of the Processor's case.

Then set the Heatsink/Fan combo on top of the Processor, and tighten the screws down in a Criss-cross fashion

3) Tighten one screw down one turn. Go to the Opposite Corner, tighten that screw down one turn.
Skip over and tighten the other two screws down one turn as detailed above. You are tightening in an X pattern.

Make SURE the Heatsink's bottom is flat and level on top of the Processor's case.
If it is tilted even slightly, the heat transference won't be worth writing home to Mom about.
The Processor will overheat, and the fan will spin at high RPM's.

4) Is the Fan cable (Wires) plugged into the motherboard tightly? Plugged into the correct fan connector on the motherboard? (CPU_FAN)
Does the motherboard's Cpu fan connector have the same number of pins needed, as the fan cable connector requires?

B) If this Heatsink/Fan combo, (Sanyo A38001-001) has been installed for quite some time, check to see if the Thermal Paste has dried up, or is drying up.

Since 2004?
Yep, you better pull that Sanyo A38001-001 off, and check the Thermal Paste.
Computer unplugged from power, OBSERVE Anti-Static Precautions.
A Processor is the most susceptible hardware component to Static shock.

Clean the Processor and bottom of the Heatsink as stated above. Properly apply fresh, new Thermal Paste.

Example of Thermal Paste. (Maybe there is a 'Mom and Pop' computer store near you, that you can buy a one Processor application, for around $2)

Check for a loose Cpu fan cable connection.

Make sure the Heatsink/Fan combo is seated tightly on the Processor.

Have any further questions please post in a Comment.

Ok I cant find a model number on the heater, it has some info like Gulf Stream super heater, scroll inside and Titanium inside, 106,000 BTU The pool filter gets cleaned every monday by a pool service...

There are a few things that can cause a heater to not fire up. One is, if the flow sensor is not working. There can be sufficient flow, but if the heater cannot sense it, it will not light up. Make sure that there is enough flow. Another possibility is there could be a build up on the thermal couple or the burners that is interfering. Those do need periodic cleaning. You should be able to check the thermal couple without disassembling the gas line. I would not recommend tampering with the gas system unless you are confident with what you are doing. If you feel uncomfortable with something, it is probably a good idea to contact a professional.

Combo lite/vent fan/nite light affected by heat?

There's probably a thermal switch in the fixture which turns the fan on when the lights are on for a period of time and heat accumulates in the fixture. It sound like the heat from the attic is setting off the thermal switch. When the attic heat drops, the fixture works correctly.

This is a catch 22 situation, because if the upper housing in the attic is insulated from the attic heat, the insulation will prevent heat dissipation from the heat generated by the fixture's light bulbs. So, for safety reasons, the upper housing should not be insulated.
I'll need to work on this to come up with a fix.

Need to change light on old nutone heater

If there are no visible screws and no knob in the middle of the grate to unscrew you have a model which simply pulls down. If it has been up there for a while it may have been painted over so you will have to use a razor blade knife to cut through the paint around the perimeter. Once that is done, use a putty knife to carefully pry the grate away from the ceiling about one inch at a time, working your way around from side to side.
