Can I Plug Chassis Fans Into Cpu Header

07-15-2005,11:58 PM

Okay, this is the fault I am getting later installing my fres powerfulness provision.

The fan in the power supply is running I can hear and see information technology turn. What exactly is the chassis fan? Is that the one that is happening the mother board? If so, what steps make out I motive to take to correct this problem?

My computer model is a Compaq Presario 5415WM.

Information technology has an Intel Pentium 4 1.5 GHz processor and 896 meg of Random-access memory.

The rest of the hardware in the computer is original except for the video card and the slave push.

The power supply that I purchases comes from a third party company because the wonderful knowledgeable people at HP couldn't give me the answers I needful.

The power supply specifications are 235 watt, steady state, power factor correction (PFC). The one and only that I purchased is an original from the posture of data processor I have just is refurbished. Like I said before, however, it does work because when I obstructed in the computer it began whirring out as soon as the computer was steamy.

When I get this error (514 C.P.U. or Chassis Fan Not Heard) I can non do anything. It gives me the option to boot from F1, do a electronic network kicking from F12 or modify the settings at F10. If I choose F1 information technology will set out to check a GUID issue simply comes back "not system disk, supercede or insert right-minded disk." There are no disks in the computer that would represent causing this and I did try to see if booting with the Recovery CD would work, but it caused a CRT screen to come up that said, "Forebode HP Technical school Support." This is unquestionably not on my top ten things of fun things to do at the moment.

I did search for this problem and establish one thread still, it seemed that either the person solved the problem themselves or No one here knew the answer. I'm hoping that maybe individual does know the answer or has had the same problems I'm having and ingest right news (it can be fixed) for me.

Thanks,

Either the PSU cooling fan or the CPU heatsink fan is not blocked into a motherboard header. Look in your owner's non-automatic to locate the three-pin headers labled CPU and CHASIS, which are happening the motherboard, and take bound fans are engaged to them. Some BIOS settings have a safety that prevents the system from functioning if fans are not plugged in to these headers, especially the CPU header. Unfortunately, you probably don't sustain access to the BIOS settings therein COMPAQ (thanks to the wisdom of oem mfg's).

The old PSU Crataegus oxycantha give had a fan sensor wire that blocked into the mobo that the new PSU lacks.

It is giving that erroneousness because the BIOS itself has a sensor connection for a soma fan that is not in wont at the moment. (Meaning, either a front operating room rear cooling fan is non plugged-in to the apposite cope on the motherboard!). Delight check to catch if you have a cooling fan that is non connected! Also, there is a possibility that you've gotten the fans connected to the dishonourable coping connections on the motherboards. (CPU fan connected to chassis fan header and chassis devotee connector to Central processing unit devotee header!). Which would give you similar errors since they are too detective work current draw Eastern Samoa well as fan fastness and having the wrong fans connected leave ease up such errors!

The original unit Crataegus laevigata ingest had a P7 or P9 3 flag powerfulness add winnow connecter. On that point are correct replacement units that should have a stacked-in fan control that should non need this connective. Since you exact this is a refurb I detect it suspect. Call your dealer .

The only problem thereupon is that I harbour't touched anything to do with the lover on the motherboard. I give all the wires from the brand-new power supply plugged into the ONLY places that they would fit and believe me I looked for each my possibilities before I started plugging them in. There is only combined conducting wire left from the power supply and information technology would plug into another drive wish a floppy drive. So, I possess pretty well decided that the power supply is plugged in by rights and as I aforementioned earlier I haven't touched the other fan.

Also, this power provision is an original from my sit of computer. Information technology's been refurbished to put to work properly and consequently, should have all the wires it came with in the beginning thusly, I'm non sure that would be the problem either.

I just know I'm tired of dealing with HP about this because they don't seem to have a clue A to what they are doing and anytime you utter to tech support totally they seem to care about is acquiring more of your money. I rightfully do hate tech suffer that charges, whether or not the warrant has conk out. Information technology genuinely hurts the consumers.

So, this is where I am perplexed. I haven't seen any loose wires and at that place is null I tin reconfigure as it tries in addition rising. Could I just need a new motherboard lover or is that something I would sustain to buy along with a new motherboard? If that is the case the new powersupply is going back and I'm just going to go buy a new figurer...somehow.

... Information technology gives me the alternative to boot from F1, do a network boot from F12 or change the settings at F10. If I choose F1 it will begin to check a GUID act just comes back "not system disk, replace surgery insert correct disk." There are no disks in the electronic computer that would be causing this and I did try to go steady if booting with the Recuperation CD would do work, but it caused a CRT screen to come up that said, "Predict HP Tech Support."

This is starting to smel more similar a hard drive OR motherboard trouble. Try reseating all the cable connections to everything (both ends

), including the case connectors . Perhaps one was loosened during the psu replacement. Also, reseat the force, video and pci cards . Moderate the mainboard for bad caps, http://www.badcaps.net/ident/

During power up , press F10 to see to it if you can access the Bios Setup. So, Load Bios Defaults , salvage and exit.

You haven't explained what led to the psu renewal , but a psu nonstarter operating theatre powerfulness heave ( ex. lightning) can damage other system components. If you have a diskette drive , then its come-at-able to check if the velar push back(s) are hunky-dory with a W98se bootdisk Oregon the hard drives manufacturers designation public utility disk.

Here's the nexus for the replacement parts that make ascending your system:

hypertext transfer protocol://www.partsurfer.hp.com/cgi-BIN...%3F&catsel=%3F

As you can see, it lists 3 different might supplies, which is why maybe you are having a problem! Information technology could take over been unity of the other two part numbers that you necessary ready to correct the trouble.

Until you can verify on the nose which one you needed as the refilling, you're always going to be unsure whether or non the top executive supply that you just installed is the letter-perfect extraordinary or not.

The other two listed power be the ones that would process and non the one that you give birth on-hand. If this is a refurbished unit, then information technology is more likely that they also replaced surgery change the separate turn label on the world power supply just to be able to deal it as your replacement part. Incidentall, which keep company did you buy this replacing PSU from? I know all of the different suppliers of replacement Compaq, Dell and Horsepower parts since the company I work for does the identical thing. Please double check the part number happening the replacement part and equate it to the one that failed to make sure that it has that same number of connections and that the labels on both for the specs are identical.

I bought the replacement character from WWW.ambry.com. That is the place that the HP employee I had been transaction with suggested. I went through ALL the power supplies they had catalogued and NONE of them worked. They weren't consenting to give me whatever keep on the problem right because the warranty on my computer was taboo. It was as if purchasing a original part meant nothing when that is the part I was truly wanting support on.

So, I think I have a wonderful computer, that really has a lot of what I want in a computer that is just over 3 years rusty and I can't use it.

There should seriously be a police force that says computer manufacturers need to keep original parts for substitution for busy five years. It sucks to pass sol much money happening something and not be able to use IT after a few years.

Look for an inactive three pin fan header connected the board and try plugging any old spare fan into it. That will plausibly fill the BIOS.

Can you take in that the Central processor buff is turning?

"Not-organisation disk" could indicate that a data cable operating theater molex cable on the system drive are not seated aright. Check the data cable at the board likewise.

hi, have you found a fix for this problem. Im also having the equal job. Nothing has change.

Do you have option within bios to bypass the chassis fan ?

my chassis does not have a fan, only the cpu sports fan and power supply fan

07-25-2005,01:07 PM

What was wrong with the original Great power Supply that caused you to have a refurbished one installed?

Could it be that the original issue also took the motherboard with it? Or that the novel problem was with the motherboard rather than the Power Add?

On a similar thread........

I am trying to quiet my Compaq DL380g1 by replacing the cardinal internal grammatical case fans with quieter versions. My problem is that the existing fans stopper directly into the motherboard using 5pin (one of which is not connected) connectors (non-molex). The fan itself has 3 wires (red, black, yellow) only goes to the 5pin motherboard connector as
Yellow ( I assume this is +5v dc)
(no connect)
Red ( I assume this is +12v D.C.)
Black ( I assume this is base)
Black ( I accept this is ground)

ANYWAY, I went knocked out and bought some susurration fans to put back these noisey fans
and none of them have this 5 pin motherboard connection. I experimented and reliable splicing the red to red , yellow to white-livered, Afro-American to black , only keep down getting a BIOS computer error that tells me that I dont have a Power Issue Beaver State CPU fan attached at bootup.

I accept the Compaq "Inauguration" CD for the system of rules.
Do I need a BIOS upgrade?
Put up I block off the FAN monitoring in BIOS?

Hmm, hijacking somebody elses thread is a bad idea.

In any event, I went prohibited and bought several whisper fans to substitute these noisey fans
and none of them have this 5 pin motherboard connector. I experimented and tried splicing the red to red , yellow to old, black to black , merely keep getting a BIOS fault that tells Pine Tree State that I dont have a Power Supply or CPU fan attached at bootup.

I own the Compaq "Inauguration" CD for the system.

Commode I shut in off the FAN monitoring in BIOS?
