Can I hold my chipset fan for 5 secs after the comp starts without it breaking?

[entropy1982]

thanks for any help

...or you can just unplug it for 5 seconds.

blah i dunno where it is... and my p180 has SO many wires in it lol where woudl the motherboardchipset fan plug into anyway?

dude if you cant figure that out by yourself, you dont need to be playing around inside the case. :roll:

.... thanks

 

[entropy1982]

would be nice if you told me instead of saying that tho =)

Um, am I missing something here, or couldn't you just look at the chipset fan on your mobo, look at the very short wire coming off the fan, and follow it to its header on the mobo? The header should be within in an inch or so of the fan. I'm not trying to be sarcarstic -- that's really all you need to do (I'd think). Oh, and unplug it before you power up. Connecting & disconnecting mobo connectors with power on is not the best of ideas.

BTW, if you do identify that fan as the culprit, Zalman makes some really nice passive chipset coolers. A nice heatsink on there instead of a fan would mean never having to deal with this again. (I assume you're referring to the northbridge fan on your mobo? If you're referring to the CPU fan, I assume you know to NOT unplug that even for a second with power on.)

EDIT: Okay, to satisfy the absolutists here on Anandtech [how could I have forgotten? :laugh:], I'll amend that last sentence to say, " ... NOT unplug that for more than a few seconds with power on." Generalization succumbs to specificity.

 

[tyborg]

it depends. Under the fan, how hot does its heatsink run? if it's not very, it'll take a few seconds for it to heat up to a critical point. Won't be super-healthy for the fan though, and don't reccomend it much. But I once got my finger stuck in a CPU fan for a few seconds about a month ago (bizarre accident) and I still use the computer today, so, yeah.

you can turn on the computer without a heatsink for a little over a second, so you can definitely run it for 10-15 seconds without a fan, maybe longer. some heatsinks dont even need a fan for processors up to an x2 4400+! the scythe ninja comes to mind...i own one and can backup this claim.

anyway, just look at it and follow the wires. its not complicated.

Dude if you cant figure that out by yourself, HTF did you build yourself a system ???. :roll:

Fixed.

 

[entropy1982]

hehe... i never looked inside before asking sorry... the wire is right by the fan =P... culprit was actually this ( http://www.newegg.com/Product/Product.asp?Item=N82E16821104104 ) piece of garbage .... it was making this "clicking" sound over and over and over... would newegg give me my money back or am i SOOL?

now that i unplugged the disc drive.... i can't see my PATA drive anymore... weird... good thing i don't really need it =P ... anyone know what it could be tho? the only thing i changed was uplugging this disc drive from the floppy cable (then i tried uplugging the cable from the mobo) and the usb cable (required to be plugged into the mobo for it to read the difft types of cards).

thanks

sorry for the newbness before =P

Depends on the CPU & cooler. I would respectfully challenge your claim that one could "definitely run it for 10-15 seconds without a fan, maybe longer ...." I saw a picture somewhere awhile back of an utterly incinerated Pentium, and the caption said something to the effect of the guy having forgotten to plug in his CPU fan and "in less than 10 seconds, this was the result." I can still see that picture in my head. And since the OP doesn't have a Scythe Ninja, I'll stand by my generalized recommendation.

I personally would recommend swapping out a suspected-bad CPU fan with another fan as a way of isolating it as a culprit, rather than unplugging it entirely, but that's just me. Or just unplug the northbridge fan (if there is one), and if the offending noise is still there, it's the CPU fan (or, I suppose, a case fan). Again, though, it depends on the CPU & cooler. I don't doubt there are some CPUs that could survive 10 seconds or more with just a heatsink on them, given the right heatsink. Just seems to me that chancing it could prove expensive. :Q

For discussion purposes, we both know that many modern CPUs have auto-shutdown anyway if the temp gets too hot, but it's not real good for the chip to get that hot even once.

I think he was referring to a northbridge fan anyway, so the issue is more or less moot.

 

[Ken90630]

'Ya know, I knew ... just knew ... that you were gonna determine the culprit was somethin' other than a fan! :laugh: All that earlier typing for nothing! :laugh:

Glad you found the prob though. I'm afraid I can't quite make heads or tails of your current dilemma, but then it's late and I need some sleep. I'll let one of the other guys tackle that one for you.

And no need to apologize for the "newbness." God knows I've posted my fair share of newb questions over the last couple years. At least you were willing to take advice, which many newbs here aren't.

Now go unplug that CPU fan like BigsmOOth suggested and see if your CPU will last at least 15 seconds without burning up. He said you can send him the bill for a new one if it doesn't work.

Put away that flamethrower, BigsmOOth. I'm just kiddin'. :laugh: Actually, it would be pretty cool if we could all get rid of those noisy CPU fans. Noise is the main reason I replaced the stock cooler on my Athlon with a Thermalright/Panaflo setup. Silence is golden.

i understand what you are saying and ive seen that picture, but i dont think that happened in less than 10 seconds. if it did, it was because the guy either didnt mount the heatsink right, didnt use thermal compound, or a combo of the two. copper and aluminum both have a high enough heat capacitance to keep a processor from cooking itself for 10 seconds. i doubt many would keep from throttling or auto-shutting down after that period but im sure newer cores (aside from the prescott) could hit the 10 second mark. sorry, i dont have data for that because no one really cares to test it...i just know how to calculate how much thermal energy a metal block can absorb and how much heat a processor can output per second. its really not hard to figure out, but i have a physics test in 9 hours so i need to go study.

Clicking sounds are more often made by a failing hard drive... unless you meant a rattling sound.

The fact that your drive seems to have dissapeared means that it may have been the true culprit!

Floppy drives only click when you boot, check or access them.

 

[entropy1982]

well no i took my floppy drive out of the case while it was on and listened right with my ear on it.... i felt the vibrations coinciding with the sound and the sound coming directly from it and it wasnt those kinds of clicking sounds... they were very repetative and consistent

 

[Some1ne]

so you can definitely run it for 10-15 seconds without a fan, maybe longer. some heatsinks dont even need a fan for processors up to an x2 4400+! the scythe ninja comes to mind...i own one and can backup this claim.

All of you debating how long a CPU will last without a fan know that the poster was talking about disconnecting his chipset fan, and not the CPU fan, right?

Also, most of the time if you have a well ventilated case you don't actually need the chipset fan. A passive heatsink should work just fine.

Yeah. Read the thread in its entirety and I think you'll see how/why those things were discussed.

Who knows ... I just remember the caption. I think it also said something like "Don't try this at home, boys & girls." Presumably the guy didn't time it with a stopwatch -- in order to do that, he obviously would have had to know his fan was unplugged, and he obviously didn't! :laugh: Expensive mistake. :Q Actually, I've seen several such pictures over the last few years, and I just don't remember exactly where I saw this one. I think it was online, but it might have been in a computer magazine. I might have saved a screenshot of it or something; I'll PM you with it if I ever run across it again.

If memory serves, I think it was an early P4, if that matters. But I'm not 100% certain. Shifting gears slightly: Which stock coolers do you think are better -- AMD's or Intel's? I don't use AMD's stock coolers 'cuz I think they're too noisy, but I don't have any personal experience with Intel's.

 

[Aeridyne]

heres my suggestion dude. Get yourself a spare cheap mobo that works and an older power supply that has the power on button right on the power supply. (Lots of older pentium 1 generation machines have these.) hook up any of your suspect fans to the test power supply and listen to them. Then if none of those sound bad, remove another suspect fan from either your cpu or northbridge, take that fan and hook it up to one of the 3 pin connectors on the spare board and listen. This is a foolproof way to find the loud fan and with no risk to your good system. Just be careful if you do take the fan off your northbridge, it can be tricky, i recommend testing that one last.

actually i am the exact opposite of you when it comes to stock cooler experience. i only know about intels! they have always been more than sufficient, even for some mild OCing. pretty quiet too...

i didnt even put the stock cooler on my x2. i got it out of the box and put on a ninja.

 

[Ken90630]

Interesting. If I'd have had to guess, I prolly would have guessed the Intel CPU fans would be noisier since their chips run hotter than comparable AMDs. Maybe their heatsinks are beefier or maybe their chips can run hotter without damage or somethin'. I just know the Athlon CPU fans are too noisy for my purposes.

I'll have to check out those Scythe Ninjas. I'd never heard of 'em before you mentioned 'em.

Just hold it, it will befine. Thats what i do to trun things down in smartguardian. Now my case is running strong and silent
