Firstly i'll like to say that the swiftech MC462 is huge and heavy too. sadly it is not working the way i expected it to. i'm currently overclocking a 1.4GHz T-bird to 1518MHz with 138x11. problem here is that the temp. is at 55C at full load. now i believe that is abit to high for a Heatsink that big. could it be the way i screw the heatsink down to the board which is wrong? can anybody tell me if i am doing it right? i'm also running at default voltage and if i even try to pump up the voltage to 1.6v, it will not even boot. could it be due to the heat? i have alot of questions but i'll stop here 1st and hope this questions someone can help me with. thanks in advance. oh, i'm using an ASUS A7V133 MoBo.

i have no idea what AS2 is but my chip is an AYHJA 0129. hope this helps.

Good choice on the heatsink. This may sound silly but did you install the heatsink EXACTLY how the instructions said? did you use the plastic washers or the fiber ones? Did you only tighten down the heatsink screws a little, not alot?

well yah, i guess i followed the instruction correctly. i'm using the fiber washer as here where i buy it, that is all which is given. i tried tightening down the screw a little and then alittle more till the point where i cannot screw it anymore. i spend 3 hours taking the fan in and out just to tighten the screw so many times. i wonder if i change the nuts to metal ones, will it help as the plastics ones at lose already.
AS2= Artic Silver. Do you use any kind of thermal compund?
I also read in another post of your's that you ambient temp's are at 30-35C. I think that's also a big part of the problem.
How about case cooling?

Try checking temps in bios instead of asusprobe. Asusprobe got a bug which makes it show 10c too much so actually ur temps are 45c which is nice:)
Download motherboard monitor5 instead, which shows the right temp!! I got exactly the same mobo as u so i know
My A7v133 was 10* more than the temp probe I placed next to the CPU , The MC462 is doing the job if installed properly.
I doubt there's your temps are actually running that high...
Asus boards are notorious for showing higher temps than the cpu is actually running at...likewise, Abit boards usually show lower temps than the cpu is running...
that's why you see some of these crackers posting 35C and below running @1500+ when in actuallity it would be impossible to do this with any conventional HS/fan setup unless the ambient temp was around 15C.
my advice: don't worry, you're probably running @ about 45C so you're fine...oh, and watch the footpegs of your processor when changing the heatsink...
one of mine just fell off, I didn't notice it, and I crushed the upper right hand side of the chip when installing the heatsink...bummer :(

well yah, i'm using thermal compund but it has no brand on it. i believe that so long as it is a thermal compund, it should do the job. anyway apart from that, i have 2 fans blowing air out of the case. both of which are placed behind. i tried last nite at full load the mobo temp. reaches 40c. how do i drop that to maybe 35c? which chip on the board needs another heatsink? i have checked it in the BIOS but it shows the same temp as showed in ASUS Prob. i spend RM330 on the MC462-A and i'm really expecting result, result which i am not getting. i guess the HSF is a good one if placed corretly..........how will i know if i have placed it correctly? i hope somebody with the same board and HSF or knows about this can help. i'm in need of help.

i'll also like to say that i have an external prob with this wire coming out of it that i us to place very very close to the chip under the huge HSF. can u imagine what i am saying? the temp showed by the prob is 5 - 7* lower then what is showed in the BIOS and ASUSProbe.
Make sure you've got the fan on your MC462 oriented correctly. I believe the label should be DOWN so that the air blows down onto the heat sink. I had a slight problem with that, checked my temps, and had to reverse it. (Before I switched to the Golden Gate 40 that is)

i've tried both ways. blowing air onto the heatsink and sucking from it also does not work. my temp is still at 55*c. i notice that when the mobo temp increase the CPU temp increase also. maybe if i can keep the mobo temp low then this will help my CPU to stay cooler. your think it will work?
Get motherboard monitor at

Install it and see what the temps really are.
Then check the temperature of your room. If the temp of your room is 35c you're going to be running at 55c if not more.
I've got the same heatsink and i'm running at 44c under full load and 35c idle. Case temps are 25c.
Artic silver will help. But only by a couple degrees.
