I could buy a Del Inspirion 24 7459 (16GB memory, i7, 2016) second hand. There is nothing wrong with it, except for the cpu that is getting hot and the fan is spinning loud. Windows 10 is reinstalled, unnecessary software is deleted.



I was wondering: what can I do do to make the cpu run as normal? It is not constantly at 100% and still the cpu gets hot.


Is new thermal paste a possible solution? Are there other things I can do?

Look into upgrading the fan if possible and yes, new, quality thermal paste like Arctic Silver.

Define hot. As in what temperature range are you seeing?

What I've seen is around 60 to 70 degrees Celsius. Fan is spinning hard and loud. Only when the cpu has almost nothing to do, it calms down. I find this strange, because my older laptop (2012) with a Pentium CPU and the same Windows 10 is almost silent and the cpu is less used to do the same tasks.

And which processor does your machine have? These had i3-6th gen, i5-6th gen, and i7-6th gen as processor options.

The operating temperature that's considered Within Normal Limits (WNL) differs among them.

I also noticed that there is no cmos battery at all. And those are difficult to find. Does someone know where to get them or an alternative? I mean the whole thing: connector, wire and battery.

Would it be possible for you to post a Speccy snapshot? Instructions will follow.

The T(case) spec for an i7-6th gen is 71 degrees C, so what you describe is running in the hot end of the range for this processor. If you do not have a dusty machine interior, the heat sink for the CPU is not clotted with dust, or similar, I'd suspect something that I almost never do: Thermal paste failure.

As to CMOS, are you saying that if you turn the machine off, and unplug it for a short while, that when you fire it up all the date-time settings are lost in BIOS/UEFI? They should be if you have no functioning CMOS battery.

Using Piriform’s Speccy to Collect Your Computer’s Hardware & Software Specifications
1. Go to the Piriform Speccy Download Page and download the program.
2. Run the installer you’ve just downloaded.
a. Note: The Speccy free installer may now come with Avast and the Google Chrome browser bundled with it (or something else, what’s bundled has changed over time). Make sure that you UNCHECK the options to install any bundled software when you see the checkboxes during the Speccy install sequence. When you reach the end, uncheck the View Release Notes checkbox, then activate the Run Speccy button.
You will then be presented the Speccy Main Window:


3. From the File Menu, activate the “Publish Snapshot” item [or press ALT+F,B]:


4. You will now be presented with the Publish Snapshot Dialog:

You will, of course, activate the Yes button.

5. Finally, you will be presented with the Snapshot URL Dialog:

on which you will activate the Copy to Clipboard button so that you will have the snapshot web address to paste into your message.

Note: If you want to save your system specs to a text file, at step 3 choose the Save as Text File option at step 3. This can be handy if you need to e-mail your specs.

You can read a snapshot here:

About the cmos battery: when I opened the computer, I noticed that there is no battery at all. There is a connector, but the battery, whire and other connector are not there. The bios date defaults to a date in 2014.

As far as the CMOS battery goes, having a photo of the motherboard would help for any potential assistant. I'm not good, at all, with envisioning these. In most that I've dealt with there's a clip soldered directly on the mobo under which the CMOS battery slides, not unlike a watch battery.

Here you can read about replacing a cmos battery (with a picture of the actual part):

And here a picture of a part of the motherboard with the cmos battery connector.
