CHIPSET FAN: heatsink with tiny fan, with PLASTIC COVER: remove & replace???

question's in the title

my mainboard's PCH has this "protection" :





basically it's a small heatsink with a fan & all covered by plastic



now they call it "thermal armor"

but logic says it's more like a thermal trap because:

1) it all depends on the fan, and the fan will fail (small fans are designed to fail)

2) the plastic cover will act as an INSULANT since air's no longer blown up when the fan fails

3) NO HEATPIPE (unlike the Rampage boards) so cannot evacuate the heat out of the PCH heatsink, when the fan fails: the heat remains trapped under the plastic cover


in other words when the fan fails this protection becomes the opposite of a protection


so this smells of planned obsolescence right? they designed this to fail & damage the board by frying the PCH (Asus ain't exactly known for its ethics)


so should I remove this whole thing (the plastic along with the heatsink & fan) and just put a bigger passive chipset heatsink instead?

like this one:


at least it's "open" (not smothered by plastic) and doesn't depend on a fan

If you have decent airflow in your case I'd just unplug the fan and leave it as is. But IIRC the fans aren't even audible really ... so just leave it until it dies?

It's not like it's a 775 northbridge - the PCH on X79 on an HEDT board uses < 8w of power.

yeah I considered that but like I said if the fan is off then the PLASTIC COVER will retain the heat from the heatsink

and since the plastic cover alone can't be removed...only the whole thing (heatsink+fan+plastic cover) can be removed

Something that is only <8w likely can function without the heatsink in the first place. The plastic is not gonna hurt anything.

hey believe me even with the heatsink AND functioning fan (at 3000rmp so that's slow mode): temperature of the PCH is almost 50°C on idle (not that prime95 makes it go up so I dunno what exactly makes a PCH temperature go up)

if it's already idling at 50°C with good airflow then imagine if the fan goes out and the heatsink's covered by that plastic with zero air flow?



why didn't they just put a bare heatsink with no cover & no fan?

That motherboard is probably nearing 7 years in age now, maybe the TIM on the chipset has dried out?

actually it's new in that it was never used those past years (even the I/O shield was still in its sealed wrap)
and can't fake the "new" smell either

anyway that doesn't answer the main problem - even if everything works well at the start, for argument's sake: look at first the pic of the cover & fan then tell me: what do you think will happen when that fragile fan stops spinning?

remember that the heatsink is covered by plastic & plastic doesn't exactly conduct heat

also remember there's no heatpipe going out of the heatsink

so what happens when that fan stops spinning??

I have had the Z77 sabertooth in the past (full plastic armour) and used it with and without fans (as the manual said I could) it makes very little difference to the temps when the fans are on or off (a few degrees over extended periods). So your call. At <8watts of power I would not worry at all.

the z77 sabertooth is VERY different though: most of the mainboard is covered by plastic EXCEPT a few things like the PCH heatsink which is exposed to air (no plastic to smother it)

a bit the opposite of mine actually - look at the pics I posted in the OP - which is why my plastic-covered PCH needs a fan to blow out the air trapped by the plastic




that's no problem though I was able to remove only the plastic cover, and keep the metal heatsink : )
I kept the fan too (difference is without the plastic, the fan will blow air all around it & it won't be funnelled toward the PCH. no biggie. at least when the fan fails, the heatsink won't be covered by plastic so the hot air can escape)

!!! I tested with & w/o the fan: temperature difference on an almost empty PC is about 7°C: w/o the fan it's 50°C on idle, with fan it's about 43°C on idle, on a system with no hard drive, 1 usb flash drive & 2 ram sticks on stock speed
and that's with the plastic cover removed & heatsink exposed. imagine how much hotter it'd be with the plastic & without the fan! (again look at the pic in the OP)


>>> now another question is, what's the "best" way to "stress" a PCH?
what sort of activity in the PC makes the PCH as hot as possible? (for testing purposes)

increase ram clock?
increase number of ram sticks? (quad channel?)
increase number of hard drives?
increase number of usb drives?

theoretically if I do ALL these things at once (8 ram sticks, an SSD on every sata port, and a flash drive on usb port, then somehow do a read or write operation on ALL these drives simultaneously) how much hotter can it get compared to say, a system with no hard drive, only 1 usb drive (live usb) and only 1 ram stick at stock speed?
what'd be the temperature difference?

Hey, I've got the same board, and am looking to do the same thing. Would you mind going into detail with how you managed to remove the plastic shroud? Do you have to remove the entire fan assembly to remove it?
