Core 2 Duo E7500 Temps

[Componentgirl90]

I have a legacy machine using a E7500 Core 2 Duo. I did an intel burn test which put it under full load and it went as high as 100 Degrees celcius which is the TJ Max.

I put it under load with heaven benchmark and it ran at 80 degrees celcius (60% load).

When Idle it is between 30 and 44 degrees celcius.

The idle temps seem ok but the load temps are a bit concerning after reviewing some posts on others sites. I used RealTemp to assess the temperatures.

Are these temperatures too high? What can I do about it?

It is an E7500 but the bios must be old as it is only running it at 2.2 Ghz so that might have something to do with it. Stock cooler, thermal paste recently added apparently.

your temps are good, don't worry

thanks for the response. Are you sure, i know that you are the CPU expert and i am not. It seems to get to 80degrees too easily and it says the maximum operating temperature is something like 75 degrees.

as you have an old cpu so its ok but you can decrease some temps by applying a good quality thermal paste

What are the temps during normal usage as stress tests only show the worst case scenario.

 

[Componentgirl90]

I am not sure but 60% load was all that was placed on it during Heaven benchmark. I haven't tested it on any games.

These do run hot on a stock cooler, but the temps seem high to me considering you're only running @ 2.2 GHz instead of 2.93.

Although I was using a large cooler and fans, my 7500 was running over maximum Intel recommended voltage @ 3.85GHz and would not exceed 56 degrees after hours of 100% cpu benchmarks..

Would suggest you;

Check cooler seating/paste/dust. Ideally replace cooler, something like a Freezer 7 (Skt 775) would be cheap on eBay and so much better.

If you're not happy delving into the bios, download CPUZ to easily check actual CPU/Voltages/Multiplier/FSB Speed etc.

As a possible quick fix, assuming you are comfortable with bios settings, (It's simple not scary,) Reset to default settings. It may be someone has previously messed up over/under clocking settings.

As it seems you are aware, your motherboard may not have originally supported the FSB speed of the cpu. Hopefully there will be a bios update to solve this.

I will try reapplying thermal paste (will be good practice for overclocking other machine). I want to avoid spending unless necessary though with regards to a fan. Its interesting to hear your CPU was running at 56 degrees, quite a difference.

I am assuming that the reason the CPU is at 2.2Ghz is that the bios is probably not the latest one. I wonder if this could affect the voltages as well as the CPU speed. Therefore a bios update might be the first port of call especially as the guy I bought it from said he had just applied thermal paste.

I will give that bios reset a shot first, shouldn't do any harm.

 

[Mike Prior]

The older std bios wouldn't affect temperature (voltage) but it may have been modified.

 

[Componentgirl90]

I loaded optimised defaults and the frequency went from 2.2 to 2.9 Ghz. So the bios was able to recognise the CPU, I was mistaken. It must have been set at 2.2Ghz some other way. I ran the Intel Burn Test briefly and it hit 101 degrees celcius so I stopped it.

I wonder if the guy who sold me it underclocked it and possibly lied about repasting so to avoid the bother and expense of thermal repasting or if he did it properly.

 

[Componentgirl90]

Another possibility is that the sensors are wrong on the motherboard. I used Real Temp. Around 60 degrees the temperature really shoots up to 90s/100 in a matter of a second or two, I wonder if the sensors are accurate at all temperatures. Some sort of measurement error or something.

 

[Mike Prior]

I don't know how effective it is, but RealTemp provides a sensor test. You need Prime95 as well, but they provide a link.

Unlikely, but it may be a known problem with early bios that was fixed with later releases.

I have come across a few instances of the bios reducing the clock multiplier by itself, but in your case it would seem a deliberate action to a known problem. More so if RealTemp was already installed.

As you were told new thermal paste had been applied, my best guess is that they mangled the plastic fittings on the cooler. If you haven't done so already, I suggest checking cooler seating as your next move.

 

[Componentgirl90]

Thank you for this response.

It could be that fail safe defaults were loaded instead of optimised defaults:

I actually bought the MOBO + CPU + RAM separately from the rest of the components and installed Real temp once I assembled it all.

I will check the cooler seating. I will also apply paste as well.

i applied artic silver 5 on to the cooler and spread it before fitting to CPU. This reduced temps to 69 degrees under 60% load. 85 degrees for Intel Burn test. Idle temps were mid 30s. @2.93 GHz.
