Why is this happening?

I just got a 1.2 ghz Tbird and an Asus A7V133 (KT133A chipset) and I'm using a 55 watt peltier and Alpha PAL6035 heat sink. I've been having some problems posting when setting the ram to CAS2, but its Mushkin Rev 2 PC133 ram which is suppose to go up to 150 fsb at cas2 (and went up to 140 at cas2 on my P3 system). Anyways, the temps in the bios are:

Motherboard: 25 C
CPU: 52 C

Why is the cpu temp so high? And don't just tell me to make sure the cpu is making contact with the heat sink, because it already is. Could it be that the 55 watt peltier is not strong enough to keep the 1.2 Ghz tbird cool, and that the heat from the cpu is overwhelming the peltier causing it to not work at all? might I be better off just using the PAL6035? Or could it be that the temps are being reported inaccurately.

I'd be willing to bet that its something wrong with your peltier. Maybee you do need a more powerfull one. so much can go wrong, its hard to say. Also, i dont know whether you have yet, but case cooling can hlep too.

a 1.2 tbird unclocked is producing about 55- 60 wattsof heat i believe that the rule of thumb is double the watt`s produced and a hsf that will disapate the heat the 6035 is right on the edge

i put a 72 watt pelt on my 1gig tbird @ 1246 > 83watt`s and my temps went up (hedgehog lapped with delta fan)

Yes... as it turns out, it was the peltier. Appearently the 55 watt peltier was not powerful enough to cool the 1.2 Ghz tbird, and overwhelmed it. I removed the peltier, and just used the Alpha PAL6035, and now my cpu temp is 33 celcius idle. Also, all the post problems have gone away, ram can run fine at cas 2, i'm reformating now, and should be overclocking in no time. Thanks for your help.

whats a "peltier "
and what is posting?

and why do you set the RAM to CAS2 in the mobo? I thought if you bought CAS 2 ram, its always cas 2.....cas 3.....always CAS 3..... can't change it no matter what.

peltier is a thermoelectric "heat-pump". sandwhich of two thin ceramic layers with semiconductor material in the middle. the semiconductor has its pn junctions aligned very specifically, so when you apply current, it transfers heat from one side of the pelt to the other. you could also cool one side and heat the other, and it'd give you current. basically, put the cold side on the proc, waterblock on the hot-side and apply current. viola!

post - power on self test. what the bios (basic input/output system) does when you switch it on.

the cas settings are latency/timing settings that the mobo uses to communicate with the ram in the board. ram dimms are made as cas2 or cas3, depending on what chips they use, but you have to set it in bios so the motherboard knows. it can autosense via the spd (serial presence detect) device on the ram, but most good mobos give you the option of choosing. i have "pc100 cas3" at 142mhz cas2! :)
