E4300: temperature is too high at 2.4GHz

[Youmei]

CPU: E4300+stock hsf
mobo: Giga 965P-DS3
ram: ddr2 667
case: cooler master CAC-T05-UW, mid tower

Vcore: 1.325V, ambient T: 25C

Frequency: 1.8G:
TAT(C0/C1): 60C(100%) , 46C(idle)
Core temp(C0/C1): 46C(100%) , 29C(idle) ,

Frequency: 2.4G:
TAT(C0/C1): 77C(100%) , 54C(idle)
Core temp(C0/C1) 64C(100%) , 35C(idle) ,

Hi I am trying to oc my E4300 from 1.8G to 2.4G with stock hsf, but CPU temp is too high after I increased fsb from 200MHz to 266MHz leaving voltages unchanged. Since a lot of ppl here said there should be a no-sweat job for such a moderate OC, I am wondering if my case cooling condition is not good enough. Also, there is 20C difference between TAT and Core temp, which one is more reliable? Any good suggestions....

I guess it could be a "Case Cooling Issue".

One thing you could do is lead the side of the case off and turn it on its side so the open side points at the ceiling. This should let any hot air rise fairly easily out of the case.

Does you CPU Fan Speed Up/Down with CPU Usage? If not this could be part of your issue. Your fan should adjust itself to meet demand.

If the FAN is really spinning up, perhaps there is something amiss with the CPU/Heatsink connection.

I would guess your CPU HSF isn't seated correctly. 60C seems a litte toasty for such a cool running CPU at stock.

Try the case open thing quick, if your temps drop considerably (8-10C) you found your problem. You will need more case cooling, but if temps don't drop much (probably will get a few degrees no matter what) then your HSF isn't seated right.


😳 You did peel the plastic off the copper contact area of the HSF right? Not to insult your knowledge or anything, but I've seen that happen :lol:

Always mention the stupid stuff.

One of my favorite personal examples is when the sound on my new laptop became nearly inaudible. I checked the Bios, Updated Drivers, max out the volume in control panel, used the laptops sound control function keys, etc.. etc.. Everything I could think of w/o luck.

So I reluctently call usually Helpless Support Line.

The first thing she asked if if I had tried adjusting the volume knob on the side of my laptop..........

I'm what "volume knob on the side of my laptop?........Oh THAT knob :>
Never mind and thank you very much :>"

At that moment, I doubt she would have believed I was a well paid I.T. consultant :roll:

Thanks. I opened the side of case, but the temperature doesn't change at all; then I took off the stock hsf from CPU and put more thermal compound on both surfaces (CPU/Heat sink), reboot again, and turns out that still no temperature change (actually temp rises a little, 1C). Now, I don't know what's the problem and what to do next...( BTW, how to change the speed of CPU fan?

I found another wield thing: the heat sink of chip 965 (north bridge chip) )on mobo is very hot (too hot to touch), and this heat sink sits very close to CPU socket. When I try to touch CPU heat sink, the side near to chip 965 is much hotter than the other side. Will this be an issue?

 

[zenmaster]

Before you applied the additional thermal compound, did you remove the previous thermal compound with rubbing alcohol or similar?

There could be FAN settings in the BIOS.
Try to get some utility to tell you what speed the CPU fan is running.
This often comes with the MB.

Then report the FAN Speed under load when the system is getting warm.
Also tell of if its a stock fan or different model since proper speeds could vary.

Example - On my 4300 System that I have running at 3.0Ghz, The Fan will run at close to 1000RPM, often less, when the system is idle. When under load it runs closer to 2000RPM. On some systems the FAN can't adjust itself and may need to be set to run permenantly at a higher speed.

I've contaced Core Temp and Intel regarding this problem.

E4300 only; temperatures reported by TAT are offset by +15c, and should be diregarded. Continue to use TAT for load testing. Temperatures reported by Core Temp are correct.

The Core 2 Duo Temperature Guide has been updated accordingly.

Thank you for your post,

I checked my bios setting, the CPU fan sppeed is set as auto mode. I changed it to Max speed, now the fan speed is always 2000 rpm. The temp problem is still there. I am using stock hsf.

For orginal setting: Vcore:1.325V amp: 25C
1.8 GHz: 29C/idle 44C/100% load
2.4 GHz: 35C/idle 63C/100% load

Should I change the stock hsf with a bigger one, like big typhoon???

 

[Pax2All]

When you say you turned the fan to max are you saying you disabled smartfan? Smartfan is evil

 

[Youmei]

Yes, I turned off smart fan, now the fan is always working at Max speed(2000rpm). CPU temp is 64C/100% @2.4GHz. Is this temperature safe for long time running?

 

[CompuTronix]

If you're refering to Core Temp, then yes, that temp is fine at 100% load. 8)
