What is wrong with my cpu!!!? IT IS HOT!!

I have a A64 Newcastle 3500+.

I was originally using the stock HSF and thermal pad that came in retail box, but I was getting idle temperatures of ~47C, so I bought a thermaltake polo 735 HSF.

Same temps! I cant believe they didnt change AT ALL! What could be wrong? I used a thin layer of arctic silver 5 with the thermaltake.

My case has two intake fans, two exhaust fans, and a side window intake fan.

I can't understand how it could possibly be this high?!

My BIOS voltage setting is 1.5V, but my Abit 3rd eye reads 1.52-1.53 volts? Could this be the problem?

I'm really a little upset that I bought this great copper heatsink and I am still having bad results! The fan is on manual and is running at around 4100rpm. With this heatsink and that kind of flow, how could the temperature possibly be this high? When I open prime95, it instantly shoots up to 55C! Then it climbs to about 59C.

I should mention that at the moment I am using a 200Mhz OC, running at 2.4ghz (219 FSB). However, even at stock, the temperature is the SAME! How could this be?

I am so confused, please please help!!

Edit: My CPU temp HAS to be wrong (in BIOS and in my 3rd eye), I just pulled off window and touched the HSF, is it almost cool to touch. There is NO way my cpu is nearly 120F and my heatsink is cool! Grrr!!
 
I have your exact HSF combo! Try thermal throttling, where you put the heat sensor very close to the cpu but not ON it. The sensor should be taped to the bottom of the HSF and should be as close to the cpu as possible with out touching it. It's not a good idea to run the cpu on manual since thermal throttling does a much better job. Try that first, and use a program like MBM5 to see your fan speeds. If you see speeds at like 4000-4200RPM, then it's between 38*C and about 42*C. When you run prime 95, be sure to check the fan speeds at ALL times because the fan speed is directly associated with the temp. The fan will max at at 5500RPM which is 55*C and if the CPU is REALLY getting that hot, then it will max out the speed. I have it on a P4 Northwood 2.8C and idle it's at 39*C currently but underload it can go up to 50*C and rarely 55*C (summer possibly).

Here are some things to consider:
1. Abit boards measure too high of temps so if the temp is actually 40*C it will be measured at 52*C or something like that.
2. Thermal throttling IMO is the best way to go for CPU temps since it automatically slows down when temp is lower
3. By using thermal throttling, you have an idea of what your CPU temps are, which lets you "relax or tighten" the temp readings in MBM5. So for example you could make it do -12*C so it would match the actual temp.


Checkback with your results.

BTW I am currently running prime 95 to check for temps and with my 1 case fan running @4800RPM (manual control) the case temp is 18*C and the CPU is currently at 45*C (It jumped to 50*C and then declined as I raised the case fan speeds).

When I said my CPU is idle at 39*C, it meant my case fan was running at the lowest speed possible (for quietness) but when the case fan is maxed out and the CPU is idle, the CPU temp is 34*C. Possibly you need a better case fan(s)? 1 Case fan seems to do the trick for me...
 
I originally tried the thermal control, and it would only let the RPM be around 2200rpm or so, 2400rpm under load (maybe a little higher under load). I switched to manual, because my CPU temp did not come down at all. Funny enough, it doesn't come down at all even with the fan blaring at 5500 rpm. It reads the same (even fluctuates up a degree) when I put the fan up all the way. I am leaving it at 4400rpm for comfort.

I placed the thermal sensor on the heatink on the outer edge, just away from where the proc would be (so it is not actually directly between the proc and HSF, it is closer to the edge). It is actually exactly where the picture in the polo instructions said to place it.

Is it a fact that abit mobos read high temps? It is now reading 50C at slightly loaded (hardly at all). If this is the case, I can just ignore it 🙂

I have three readings available for temp, CPU, SYS, and PWM, my CPU like i said is 50C, my sys (ambient case temp) is 34-35C (with side panel off) and my PWM temp is 38C. If sys is my case temp, it seems high, because the side panel is off! With the panel on, it is around 37-38C. I already ordered some high cfm case fans to fix the flow up, but still.

Screwy stuff going on here, any thoughts would be helpful 🙂

Edit: Just put the polo back to thermal throttle, and the rpm is ~2800-~3000 when my cpu is reading 52C. Assuming the thermal throttle is working properly, I guess my heatsink isnt actually hot (who knows about processor heh).

Edit: Perhaps I should also note that when loading windows (before entering windows) my CPU reads a temperature (on the 3rd eye) as like 35C, then as soon as it enters windows, instantly jumped to 47C or so. I am surprised the tmep can jump 10C in one refresh (1-2sec) of the 3rd eye. Something must be wrong with the sensor.
 
No motherboard sensor is perfect, and many are far from perfect. Most motherboards report the temps off, but all that really matters is whether or not the rig is stable. Download prime95 and run it overnight. If you computer doesn't get any errors, then you computer is stable and your temps are fine. If the temps were truly that high the computer would probably crash while running prime.
 
Good, I see that your RPMS are actually quite low, so that would mean your temps are 28*C (2800RPM) to 31*C (3000RPM) because agian fan sensors (are not perfect). Adjust the sensors with another program so that it matches your RPMS for you fan and you will have much more accurate temp readings. Remember, if your fan is spinning slowly like below 4000RPM then your temps are very good.
 
See if there is a BIOS update for the board.
Abits are known to read high, I believe.

Personally, I agree with FrustratedUser, what's all the fuss with those temps?

BTW, pwm stands for Pulse Width Modulation. This is the temp of your main mobo power regulation chip.
 
You AMD guys always seem to be in "hot water". I'll bet more AMD users go for water-cooling than Intel P4 users -- as a percentage of total [AMD or Intel but not both] users.

[Just jokin' aroun' here . . . 😀 ]
 
I'm not quite as worried about my temps now that I hear what you all say. I was a little concerned because I always thought that 135*F is pretty hot for a chip! My old P3 used to shut down or have problems if got over 120*F so I was a little concerend. It is probably a bad reading, it usually reads about twice whatever 10% of my 735 fan speed is (which is supposed to be about what the cpu temp is). I will check for a BIOS update, but other than that, I'm just a little ticked that I spent all this money ~$100 to cool it off and got no change in temp 🙂 (well I guess I haven't gotten in my new case fans, but still). Thanks for your help guys.
 
That motherboard (I have one) I suspect is WAY off in temp reading. I have a thermaltake silent boost K8, and it reads 43-45c idle and 59-63c full load, and I am sure thats not right based on my other 5 Athlon54/Opteron boxes.

Yep, I had the same problem with my K8USA. It read way high, and when I switched to the AN50R the temp dropped 12c with everything identically setup. Temps vary from board to board, and often even between bios revisions, so if the cooler isn't too hot to the touch and it is stable, fvck it IMHO 😀
 
Yeah, I have the same exact CPU running at the specs stated below, and I've run Prime95 overnight repeatedly with no problems even though the CPU reads in the high 50's. I don't think you have anything to worry about. Although someday I might treat myself to a watercooling system.... if it didn't wind up making my computer look too much like a fishtank 🙂~
 
if you got that many case fans (2 front 2 back as i understood) you should definitly remove !! the side fan as it may disturb the air-circilation (my ** englz skillz sry=).
 
Hey, not to hijack your post, but do nF3 mobo's (DFI to be exact) read high usually too? Because i'm getting about the same temps on my DFI with a 3400+ nc. Thanks!
