Am I running too hot ?

I just purchased a refurbished Lenovo T420.

It has a Intel Core i5 2520M @ 2.50GHz processor with Sandy Bridge 32nm Technology.

It came with 2 x 2 GB = 4 gb of ram, and I replaced one of the 2's with an 8, so I am running 10 gb total with Win 7 64 bit.

The laptop has a 128 GB ssd drive and seems to be pretty fast for what I need.

The only thing that I'm concerned about is the Speccy temps show me that my cpu and motherboard routinely get to 70 C when at idle.

Is this normal ?

Hello Buccaneer,

 

Couple of questions if I may;

 

What were the temps when you had the 2 Xs 2GB sticks in place.

 

Do you have the notebooks power plan set to Balanced.

 

Did you check the notebook specifications before purchasing and fitting the 8GB stick, this because the Detailed specifications here state the following;

 

Memory

PC3-10600 Non-Parity (NP) Double Data Rate Three (DDR3) Technology
Two SO-DIMM Slots
The use of 1333 MHz SO DIMM memory is recommended for this system.
1 GB, 2GB, or 4GB memory
Supports up to 8GB maximum memory
2GB, 4GB Intel Turbo Memory (selected models)
 
Notebook CPUs do run hotter than desktop processors and the thermal shut down temperature is therefore most often higher, your CPU for example is safe up to 100°C but at the same time it should not be allowed to run any hotter than 70°C for prolonged periods.
 

As an asides Buccaneer, did you miss the last reply of RKinner to your thread here

First of all, thanks for your reply philpower2 !

 

* I did not have Speccy or HW Monitor installed when I first used the laptop, so no, I did not check the temps with the 2 x 2 ram

 

* Yes, the power plan is set to balanced.

 

* I did not check the specs on the laptop before throwing in the 8GB.

I was under the impression that with a 64 bit OS, you could run as much ram as you wanted.

I have removed the 8GB and replaced it with a 4GB so I am now running a "legal" 6GB

If I decide to keep this laptop I will perhaps just use 1 8 GB stick.

 

The HW Monitor tells me that the cpu is running between 37-55 C at idle.

I am not sure why when I looked at Speccy the cpu and m-board were up at 70.

Is there a way to stress test the cpu and m-board to try and determine if I should keep this refurb or return it ?

 

I will, later today, run a You Tube video with 4-5 other windoews open and see what kind of temps I get.

 

* Thanks for that link to RKinners last comment; he was very helpful; and I will reply to that thread later today.

 

I remain amazed at the level of expertise here.

I live near Roanoke VA, and the local pc repair shops don't appear to be any more knowledgeable that a sales clerk at BestBuy ! =)

You are most welcome, thank you for your kind words and update Buccaneer  :thumbsup:

 

A 32 bit Windows OS will not see any more than 4GB of Ram and 64 bit versions of Windows vary, see below;

 

Your computer would be best with two of the same spec and brand of 4GB sticks of Ram, preferably from the same batch and so best purchased at the same time.

 

Third party software such as Speccy and Speedfan etc sometimes have problems with a computers own monitoring software and that is why we sometimes ask for a comparison, checking the temps and voltages in the BIOS is more accurate but those readings are when a computer is under the least amount of load and therefore not a true reflection.

 

For testing your CPU IntelBurnTest 2.54 please disregard any other product or service that may be offered at the link.

I still am experiencing what I think is an overheating problem when running 2-3 open windows.

I am getting my information from Speccy; is there a more accurate way to test this ?

What type of problem exactly.

As per my reply #4

The above is even more relevant when it comes to notebook computers, this because notebook computer MBs do not have the same type and amount of sensors that desktop MBs have.

 

Did you run the IntelBurnTest, if yes, how did it go.

Phil,

 

I guess we can call this one solved or completed.

I will continue to monitor my temperatures.

The frustrating part is that I cant duplicate the 90+ temps I was getting, but I guess thats a good thing!

Thanks for all your help !
