ok guys, so after i told you that my pc was stabilized since i had rn the prime 95. I have 3 case fans and an 80mm cpu fan working but it keeps overheating.... how can i overclock it at a lower setting?

OgiR!!

Where are you now? Still at 145Mhz and 1.700v vCore? What are your temps? We need temps from BIOS and from whatever windows utility you're using. Three case fans now? Where did you put 'em and which ones push air into the case/which ones exhaust air from the case?

After 25 responses in your last post, why can't you give us the information we need. We don't live with you and can't read your mind.

well, system is running at mid 40s (celcius) and cpu is runing at mid 60s. I watch the temps with MBM5..... As for the fans, I have one on the side and two in the back, all as exhaust.... and the cpu fan is also blowing air away from the heatsink...

OgiR!!

I checked temps in the BIOS, 39 syst. and 58 for the CPU. (Celcius) And this is while idle.

OgiR!!

If it's 58 while idle, then it might get too hot under even a normal load. By the way, what does it do when it overheats ? Does it shutdown ? reboot ? I would get rid of the fan on the side.

when it overheats it reboots, sometimes it just kicks me out of the game and i get an error message. and also sometimes it completely freezes.

OgiR!!

Unplug the side panel fan.
The cpu fan should blow air onto/into the heatsink. Fans have arrows on one side to show you the direction of rotation and airflow.

Set cpu to default of 133Mhz in BIOS
Set vCore to 1.65v in BIOS

You can always go back later.

Why did you install all those fans?? All you really need is a single exhaust fan in the rear. I don't even have any case fans on the PC I'm using right now, I rely soley on the PSU. It's an A64 3000+ overclocked to 2.5GHz & it's idling at 30C. The case does have a side air duct which sits about 1/2" above the CPU's HSF though.

Did you use paste or a thermal pad when you installed the Cooler Master? Are you sure you didn't install it backwards?

well I checked that everything was installed right. The cpu fan is blowing into the cpu. the fan in the back is blowing air OUT of the case, and I got rid of the side fan. I had added thermal paste on the cpu when I changed the fans...

OgiR!!

You're 100% sure it's not backwards? Have a look at this:

"I had added thermal paste on the cpu when I changed the fans..."

In other words, you completely removed the old thermal paste (or pad) & put a dab of paste about the size of a grain of rice on the CPU core, spread it thinly & evenly & THEN installed the HSF?

That is correct. I made sure that the heatsink is placed correctly(not backwards), and also the fan is blowing the right way. And yes i did put an adequate amount of thermal paste before locking the hs in. Now, what's the next step?

OgiR!!

I'd reset everything back to stock and see what temps you're getting then. Also, be sure that the HSF is sitting perfectly flat against the CPU.

I don't know what "an adequate amount" means to you. This pic will show you how much you should be using:

And here it is after it's been spread thinly & evenly over the core:

If you're doing it differently, there's a good possibilty that is why your CPU is running so hot. BTW, you're not using both a pad & paste, are you? You should use one of the other, not both.

Here's the complete instructions:

Jam, That's exactly how i had applied the paste onto the cpu. Also, I am only using the thermal paste (not both). My temps are at 43(cpu) and 32(syst.) while at idle. When I run games and stuff, they reach to 55(cpu) and 38(syst.). All this is happening at 133mHz and vCore 1.65 v

OgiR!!

If you would've explained things in more detail to begin with, we wouldn't have to continuely ask questions.

32/43 @ idle is fine, so is 38/55 under load. When the CPU load temp gets into the 60's, that when it should become a concern, but even then it's not dangerously high. The 2400+ has a max die temp of 85C.

One thing I don't recall anyone asking is what you average room temp is? If your room is hot, your CPU will run hot.

I don't like the temp differences between idle and load. Games don't usually stress an AMD cpu enough to show a 12°C difference...it should be more like 5-6°C.

Prime 95 or toast.exe should only show a difference that high.

I also don't like the difference a 0.50v vCore increase makes in temps.

This all tells me the heatsink is not well seated. Why? Hard to say; but if the heatsink or processor is slightly misaligned you'll not get good contact with the core. The fix is to do it again. jam linked to the how pages and you do need to be careful when setting the cpu in the motherboard and attaching the heatsink.

Many of us have tried several times before we got it right.

The vcore reading can differ under Windows versus the bios. Which one did you check ? Also, in addition to the room temp, what about the video card ? It's possible, though not likely, that that is causing an increase in the temperatures. You might have to clean the fan on the video card.

I checked the BIOS vCore value.my graphics card is clean. I have cleaned the fan and everything... My temps are now at 39 and 30 during idle.

Please make sure the CPU Fan contact to the CPU is good, may need to use more Silicon gel to conduct the heat from the CPU to the heat sink, also check the CPU Fan pins to make sure the fan socket is firmly connected to the CPU.
