The fan on my MOBO is going to die. It is an ASUS Mobo and there is a small fan over the main chip. To remove it means a total dismantle of the MOBO and then snip the pins on this fan from the back. I just don’t fancy doing that to my 5 year old PC, which I’ve upgraded with more HD (1TB) and more memory (4GB).
It’s going to die because I was getting warnings about Chip fan speed from the bios boot up screen.
I cleaned it with brush, blower, sucker etc. etc. It is Ok now and seems to be maintaining speed ( I downed “Speedfan” so I could watch it.).
But it will die in the end.
So, I was going to buy an ordinary 3 inch fan and just add it to the case, blowing on the Mobo. (With a suitable inlet of course). I’m doubling up for the time being but that shouldn’t do harm should it? Can’t really have too much cooling can you? Also, where should I take the power from for such a set up?
Oh, btw, I’ve been in touch with ASUS, because they were replacing this fan FOC for Mobo’s made 2006. They politely told me it was too far out of warranty, and that they didn’t make that mobo/fan anymore so there was actually nothing he could replace it with. Another reason why I don’t want to take the old one off.

Isn’t that a little bit much ? I can understand the 6TB if you plan on archiving a whole film collection, but 24 GB of ram ?

If you have a spare PCI slot it might be an idea to invest the few pounds in a PCI slot cooler – this is a double slot cooler but it gives you an idea…

And what processor are you going to use with it? Not the one you’ve got, I hope!

So, the Forum has raised a Change Note and a design solution has been considered. The pukka solution of “Mobo out” is not considered viable.
If you look at picture 4 above, and then imagine the new fan being 90 degrees to how it is fitted, the fan base will sit atop the sides of the Sync. where it says ASUS. The holes in the fan base will be secured to the vertical Sync walls with small heatproof tie wraps.
This will give a 1/4inch ish gap under the fan to let all that air out. Oh, I think I said it was sucking-off, but the fan is blowing-on to the Sync. Presently the air must be escaping through the gaps of the Dble sided tape, or back on itself, which is bad.
I did the change, but I also changed the fan for one with a max. of 5,000 RPM. The 8k was noisy. 2 weeks on, it’s still running just fine. The air escapes as the fan base is tie-wrapped to the top of the vertical walls of the Sync.
Now saving up for a new Mobo bundle. £1,400 worth. 24gig of Ram and 6tb of disc. Price includes the case and 1 DVD writer plus 1 Blue Ray writer and all the usual ports of course.
It will be a while, bits needed on car first 🙂

Its easy!
Ive built a pc from parts with no prior knowledge in under 45 minutes, just be careful!
By: PeeDee - 10th January 2011 at 19:00
I’ve rebuilt 3 PC’s in the last week, all with dodgy CPU fans, granted they’re c*** Dell’s, but it’s the same thing really.
Motherboard out, new CPU fan (Exactly the same as the old Dell one, only half the cost, from Aria) in, done. 20 minutes work on each PC. No re-installations of any sort, no strange taps, having to re-arrange where fans are in the case, simple!
I don’t think I’ve ever seen anyone make a 20 minute replacement job take over 48 hours.
Aye, you can do it with yer eyes shut. All I know is that most of the kit needed removing to get mobo out, and I couldn’t be arsed with the risk of it all.
CPU…in my last picture, I thought the CPU was the large fan with a vaned heatsync under it? The Graphics has a sync but no fan. The case has a fan of course, with another one in the power supply.
Anyway, it is now tie-wrapped in, 6mm above the sync. as described earlier.

Done a so called bodge job a few years back very much the same as yourself,
i did not use double stickey tape,
just a got some araldite bought from poundland:eek:and glued it on the to the heat sinc, works fine as long as it keeps the temp down then you should be fine.

It’s simple really. I aint doin it. Mobo out and rebuild is several days without PC. It’s needed.
Putting all the SW on takes the best part of a fortnight, as I will only be able to do it evenings. And that’s before I reset all my preferences for said SW.
And with a new mobo, there is “Bound” to be something I’ve got which isn’t compatible or somesuch.
By: Nashio966 - 9th January 2011 at 21:03
Dunno why all the fuss
Change the motherboard, buy a similar one with the same socket for your cpu and ram compatibility – plug your hard drives in and fresh install your OS
Variable speed as a program on your pc is a pain in the rear for many reasons, buy a manual speed controller for approx £10 🙂 Much MUCH better – will take up one of your spare CD rom drive bays.
Top option is win 🙂 – www.scan.com these guys will almost certainly have a direct replacement fan, if not have some parts that will allow you to either A) convert it or B) replace the motherboard 🙂

Hey thanks all.
The tape is temporary as I wanted to see if it was better sucking off or blowing on. I also need to think of a better way, the tape is specialist stuff (Not for this job obviously) and is incredibly adhesive. But I will do it another way.
The Thermo paste isn’t required here, that goes under the sync. This could be bolted, but the holes are gone.
Robbo is correct, the old fan had a gap all round and worked by throwing air out of the sides of the Sync.
This fan is sucking off. There is a hell of a draft coming from it (So there must be an intake from somewhere), and the temperatures are all maintaining norms. It ran 11 hours yesterday. I do agree tht it maybe better to have it blowing on. I may need to drill holes in the side of the new black plastic fan case, or snip ‘V’s around the attaching edge. This gives same affect as 27Vets Spacers.
By: Arabella-Cox - 9th January 2011 at 06:23
If the fan is screwed in place, just put some spacers between it and the heatsink. Do not operate a standard electric drill anywhere near the boards however.

The double-sided tape and any air gap around it will act to insulate heat rather than conducting it into the airflow of the fan.
T’is true. When transistors are bolted to a heatsink there’s usually a thermally conductive paste or pad put between them. Double sided tape very much isn’t a conductor of heat so it’s to be hoped the extra air the new fan shifts is of some benefit!
By: Grey Area - 9th January 2011 at 00:25
Oh, it’s all going to end in tears! 🙁
The double-sided tape and any air gap around it will act to insulate heat rather than conducting it into the airflow of the fan.
At least, that’s what it’ll do until the tape loses adhesion and your fan obeys the laws of physics – as mentioned above by Frank.
Honestly, mate, this is almost the very worst way that you could have gone about it.
Good job it’s not the fan cooling your CPU after all, otherwise you’d be in real trouble sooner or later.
By: frankvw - 8th January 2011 at 23:57
You’ve got a problem: where does the air go out? the old fan had no casing: the metal part is the heatsink. Here, it doesn’t look as if you’re making air flow on it to cool it, but more like a fan against a plate.
Oh, and from experience, tape will fail at one time or another, leading to a turning fan going amok in the case…
By: Arabella-Cox - 8th January 2011 at 22:23
Evercool, got you cool now huh! 😀
By: PeeDee - 8th January 2011 at 18:37
Decided it was time to mend it. It was taking up to 20 starts before I didn’t get the Bios warning screen telling me chip fan wasn’t working.
The Guilty
Plugged in the new fan to see if it was recognised and the variable speed was being controlled. Yep.
Time to remove old fan. If you recall, true removal requires mobo out, didn’t want to do that.
Snipped through the tin cover to reveal the actual fan. Peeled it all back and snapped off the bits.
3 small screw held the actual fan to the base unit.
What was left is this case, which I presume is acting as the heatsync.
New fan, £4.99 from Maplins. 8,000 RPM (Old was 6,000) and the blades are significantly bigger, this moves a lot more air.
Application of double sided tape and pushed new fan into the old casing.
Pikey fix, job done…..Time for a cup of tea!
By: PeeDee - 8th December 2010 at 22:39
After much advice from peeps who are “Sure”…I’m going to remove Mobo, removing minimum of cards etc. to assist its exit.
Replace fan with new one, or the equiv. availavble to me.
Returning all the same kits into all the same slots. It should then boot up as if nothing had been touched.
Due to being in China next week, followed by a weekend involving a 750 mile drive…..It won’t be until nearer Christmas, but I will update the thread just for closure. Maybe with photo’s.
