My comp run pretty stable so far from 1.2o/c to 1.4. One thing I don't like though is my temperature, the CPU at idle is 33 but when full load it reach 50C. Is this a good temperature or a bit too hot? I'm using the alpha pal6035.

although your temps are not dangerous, they are a little high. Does the 6035 have the sunnon fan? What kind of thermal compound are you using? Make sure the HSF is sitting tightly. Bend the clip to make it tighter. Add a few case fans, if you dont already have proper ventilation. Last resort, buy a delta fan for it, if you dont already have one.

I agree with tweak, that is a bit toasty. Did you use some kind of thermal grease? If you did was it applied as per instructions?

He is running at 1.4 GHz, so those kind of temps might be normal. As processor speeds get higher, their heat output goes up. Since some 1 GHz CPUs end up around 40C under load, I find it totally believable that his at 1.4 might just run that hot...

I have a 1.2 @1400 temps are 29 idle and the highest ever was 42c.I use the alpha heat sink anh have the case sides off.

50C is well within the "normal" operating temps for a tbird ...but if your like me then its way to high hehe

take the case cover off and see if your temps go down if they do then better case ventilation would be a good direction to head in ;D

Believe it or not, my [email protected] is 42-51c , idle to load. This is with a swiftech 370-0a $40 heatsink!
My case is an addtronics full tower with a 120mm and 80mm sunon intakes and 90mm outtake at back.
Case temp is 22c.
I have tried applying and reapplying arctic silver, reversing the fan (made it worse) , etc.
I don't know if this heatsink actually sucks (reviews say it's great) or that the tbird just is that hot at 1.4 and 1.85v!!!!
:p

my 1.2 gig at 1450mhz keeps at 38-42C. I am running the same HSF too (That is assuming you have a delta) Try some Arctic Silver and maybe reseating the HSF.

Your fan setup is not great. You need another fan blowing out as you are blowing in more air than you can.

I agree that the temps are high, but not dangerous if that is the highest they get.

If my fan setup is bad , how come case temps are 22-23c ? I have had this setup for about 2 years (case that is) and this is the first cpu I've had heat probs with.
I ordered a taisol (biggest on their site) to try out.
I am thinking maybe the swiftech is not sitting right - it is spring loaded so you cant really get it tighter.
The one 80mm intake on the addtronics 6896a is setup in front of the hard drive cage to act as a cooler (from the factory that way) and the 90mm outtake is factory set, too.
I have tested with a compunurse around the socket area (resistors, northbridge, etc) and nothing above 32c.
I'll definitely post results with the taisol.
I will put the 33 pabst on the taisol.

I can't say this enough. For every 10C you lower a CPU, you will see an improvement of 3-5%. By improvement, I mean stability at a lower vcore. A CPU running at 50C needs a higher vcore to OC it to the same speed than one running at 40C, than one running at 30C, etc. A secondary benefit is the lower core voltage, the easier it is to maintain at a cooler temp. Some people look at what temp the CPU destructs at and assume anything lower is acceptible.

I'm missing something here. Yes, my vcore is at 2.2V. That is what it takes to get this 650 Tbird up to 950 since my motherboard does not support FSB OC. My HSF is doing all it can to keep the temp at full load to 40C. The next step would be watercooling to get it down any further. Bear in mind that at 2.2V the wattage is somewhere near 80W! Punishing yes, Hypocrisy no.

Bear in mind that my OC setup is akin to runnin a 1.2G Tbird at 1600 using only multiplier, no FSB OC. It would probalby take a high vcore to accomplish this and high heat would ensue. The good news is that I have a KT7A on the way and I will be able to OC better with an FSB that I can raise, instead of the brute force multiplier only method. This will allow me to run the CPU at a lower voltage and hence lower temp. Not all overclockers have the luxury of a KT133A chipset.

Sorry to be the bearer of bad tidings but...
Don't bet on it m8 ;)

I'm not sure exactly what you mean by "brute force multiplier adjustment". The CPU doesn't care about either the FSB or the multiplier, it just runs merrily along at whatever total speed it is set to. A CPU running at 1 GHz 10*100 won't run any cooler than one running at 7.5*133.

Remember ambient temperatures also affect how cool your CPU will run. So, if you are living in a warm climate, it's going to run hotter than if you live up in Alaska (an overclocker's paradise no doubt ;-) ).

:p

Why do you have BOTH an 80mm and a 120mm acting as intake fans and only a single 92 mm acting as exhaust? That's got to be a horribly imbalanced setup. It would make more sense to have the more powerful 120 acting as intake and the 80 and 92 as exhaust.

Sorry, you're right, I didn't elaborate enough. If it takes 2.35V on the core to get it to run 10x100, but it only takes, say 1.85V on the core to get it to run 7.5x133, it will run a lot cooler with 1.85V on the core than with 2.35V on the core.

My addtronics case only has the 90mm exhaust at back. Like I said, My case temps are fine. Anyhow, just got my taisol 742092b today with 30cfm delta on it and now I am idling at 40c and max is 45c.6c drop at max!
I think my swiftech spring mechanism was not putting enough pressure on the tbird. I am sending it back as it cost $15 more.
I am going to get a delta 38 . I don't mind the noise as I had a fop38 before.
At least I am not so worried now.
I really like the clip on the taisol that uses all 3 notches on the socket on both sides.
I am trying to see if a place in japan will send me one of their 90mm adapters for the taisol. I saw a review that showed it knocked off another 6c-10c.
Thanks for all the input.
