So obviously I have fitted the cooler
Nothing flash Coolmastewr Gemini 2 M5
This comes with IKEA type drawn instructions.

I screwed the mounting nuts down to their thread limits, which seemed firm.

I did notice that the mounting strut were bowing slightly.

Will this eventually deform the motherboard?.

The side effect of loosening the nuts could be an unequal tensioning to
tilt or rock the heat sink and lift one side off from the CPU.

This is all a bit clumsy from the engineering viewpoint

A bit of Googling found this Guy who's tests found that clamp force
didn't affect cooling much at all

Any thoughts on this?

PS the current CPU temp had dropped by at least 20'C

I would guess I would do the same because leaving them loose is not
a good idea. Especially so if not using lock washers.

Without bothering to run down the unprovided documentation link
showing what you are talking about, I could not say.
At most, that provides expansion space for the heat sink when hot. :)

That is not good. I suggest all you need is enough pressure to have
maximum physical contact with chip and cooler for maximum heat transfer.

No locking washers in this game bits. You're talking class

No documentation either, The coolmaster website is more flash and dazzle
than info

I'll work on the hope and prayer that the cooler baseplate under the
CPU socket provides sufficient rigidity.

Sometimes Bits, you have to know when to fold 'em

I just took everything out into the sunlight to refit the old case fan
into the front of the box, It can no longer go in the back because of
the overhang of the cooler

After removing first the CD player then the front plastic fascia and
bolting the fan on, I discovered that it has 3 pin plug and the board is
all 4 pin sockets.
I am sure there is a way to get around it-- left or right bias plugging.

But I give up. One day I'll get a 4 pin fan and try again, maybe loosen
the cooler nuts also.

NOT today

regards

Thay's pretty much common on all MB's for years now. Note the slots on
the fan plug. Then note the tab on the fan header. And if you can't
figure it out from that, try reading the MB manual. It will only fit one
way.

It was during the fitting that I discovered the problem.

The fan was initially running on the motherboard - so it's possible.

of course nothing can be seen of the actual plugging due to hand being
in the way. But after I could see a separate pin on the left side next
time on the right side. Then I looked a bit closer at the socket and
plug gave up.

Next time I open the case I'll have another look at the socket and plug tab.

Or get another fan.

There are at least 3 differing types of fan plugs :

1. 4 pin 5v large old style as used with older devices (ie > 10 years old)
This has 2 cut outs on the outer socket edges to ensure correct fitment
2. 2 pin 5v for dumb fans so a neg and positive sides only.
3. 3 pin 5v for smart fans so a neg, pos and sens OR pos, common neg, pos
(this is rare but mostly on mini or m/f kit).
2 & 3 use a small plug that for one side is double lugged to enable correct
fixing so it is fitted with right way around.

If the mobo uses 4 upright pins with in a small block then you must read
the mobo manual for correct orientation if there is no slots for the plug
to fit against and these slots is the norm.


The 3 pin here is the modern norm for all fans including the CPU.

For pin specs always look at the full mobo manual although some brands are better than others for detail.

Correct Vincent.

I found this

So that mystery of incorrect plug placement is solved.

Now I will need to apply the long nose pliers and a very bright light
and some cussing to maneuver the plug into place

That should NOT be needed - at least based on my experience over the years assuming the fan and mobo are modern.

The fan plugs notches helps to sort it.

It should not be required to remove these.

When I get the time I'll have a closer look.
