Today i took apart both of my Latitude laptops for cooling maintenance. They were both running a little hot so it was time for new thermal paste and a good clean out.
Here is laptop number one, it is a Dell Latitude E5420 with a 2nd generation i5 2.5Ghz processor, 6GB ram and a 120GB SSD. I use this as my portable laptop.
Beginning strip down
Panels removed, i must commend Dell for their design of this laptop. Most laptops you have to strip them down to get at the CPU/cooling fan but this design it is simply 6 screws and 2 panels… Really good design!
The CPU with very old paste
Heatsink with old paste
Cleaned and new thermal paste on
I also blew out all the fans and grills.
Once reassembled I ran some tests and the results were great!
Full load: 87c
Full load: 62c
Second laptop is my main pc i use at a desk with a Asus 24″ HD screen. It is a little better than the first model but they are the the same to look at and of the same family in Dells laptops.
It is a Latitude E5430 with a 3rd generation i5 2.6Ghz (3.3Ghz turbo mode), 8GB 1600Mhz DDR3 RAM and a 120GB SSD.
Again we begin the strip down
This model too has the very handy panels to give easy access to all the vital parts, well done Dell!
On this model i chose to remove some of the grill to improve air flow, this machine is on A LOT and gets hammered with light gaming, HD video editing/encoding, HD video playback and all sorts of other tasks. It is always used on a laptop pad so it’s never at risk of things getting into the fan so i chose to remove some of it.
Here is the old thermal paste once again
Also blew out the grill and cleaned the heatsink
New paste applied and reassembled
After this was done, i did the usual tests and there was a massive improvement over the somewhat shocking temps i had previously
Still quite warm but nothing to be of concern and a massive improvement over an unhealthy 90c!
