Hi guys Chris here back with the Teclast F7 plus this video I'm going to show you
how to improve the thermal so it's gonna be my copper heatsink mod we're gonna
add a heatsink on there a thermal pad it'll improve those thermals and it
allow you to increase the power limit if you wanted to boost the performance
mostly the graphics performance so you don't have to do this model whatsoever
if you don't need to okay the thermals are perfectly fine as they are out of
the box so to open it up before we get started you need to remove the two rear
rubber feet because we actually have two screws hidden underneath this so once
you remove all the rear screws including ones for the SSD hatch then you can lift
the whole back off so the easy method of this mod would be to just simply place a
two millimeter thick thermal pad a nice large one right here over the top of the
chipset and just leave it at that that will transfer I feel enough heat to the
rear case to act as display a larger heatsink enough to increase that power
limit to nine or ten watts now because we're going to be touching
around the circuit board it would be wise to unplug the battery now which
I've done right here as you can see so just lift up that tape and then unplug
that connector there now you will lose any settings in your BIOS now lifting up
that heatsink you can see there is the Gemini Lake and all it had on top of it
was just a very thin thermal pad which is 0.5 millimeters thick so just cleaned
up the top of the CPU die there as you can see and I removed this zoom or pan
as the stock one that was on top of the heatsink that's just off camera at the
moment so you can use a 15 by 15 one millimeter thick copper shim fine that
I've got right here or 21 does it even larger now yes you can see all those
resistors around there that are very close to that that could cause problems
it could touch it could short but in my experience I've been doing this for
years that has never actually happened to me because when you put the thermal
paste on there and then you screw back the heatsink it's not going to move
around it'll be fine there if you are worried about that then go with
something that fits the die size precisely so go for something like
by ten millimeter one a millimeter thick shim now I've placed a thin layer of
thermal paste on top of the divers you can see I just use some Noctua this is
in th one you don't have to use a super high quality one because this is not a
65 watt disc top CPU in here this is a six watt CPU and we're going to only
increase it probably to about 10 watts and it will use 15 watts max so I've
have spread it out as you can see with a plastic bag so I just use my finger and
a plastic bag here it's just like the begging myth that I think people call it
just to put a real nice thin layer on there you do whatever method you want
there but this is what works for me now I'm gonna place a copper shim on the top
I've actually decided to go with a larger size that I've used before in the
past with good results so this one is 20 millimeters by 20 millimeters one
millimeter thick okay so I just pressed it down there is more or less centered
there and now right in the middle of it I'm going to place just a very small
amount again of that thermal pace that I've used
and I have on the back of the copper heatsink this is the stock one of course
just cut out a wider gap here now originally I'd made it for of course the
15 mil and then I had to increase that for the 20 mil that size there so it's
just going to have flush contact then with the factory copper heatsink yes it
looks a little bit crude here but I mean this doesn't really matter and I've just
spread out all over the top of the heatsink that I placed there that
thermal paste just evenly all over the top you can just put a big blob on the
top if you want I'll do it however method you want now to put the heatsink
back on and make sure you put it on the correct way and now I'm gonna place a
two millimeter thick thermal pad on the top here this is going to be
transferring heat over to the rear the bottom of the case of the laptop will
get a little bit hotter now there should be fine remember to plug that battery
back in if you did unplug it
place the tape of course back on top of the plug - that's just to keep it in
place not that it would fall out and now we need to put the lid back on so it's
gonna be a little bit harder to place on but you just need to apply a little bit
of pressure when you screw it back on the more pressure the better on top of
our copper heatsink bear all right I did find this is like a little tiny sponge
here this is to apply pressure on to where the copper heat sink is remove
this you're gonna have to remove that because now we've got a thermal pad in
its place and here what we want to do is go along and just where it says power
limit one enabled just disable that that's disabling your power limit so
I'll use all the power at once but we still need to run the software unlock
method if you want the best gaming performance here you see I have the
power limit disabled so you go out of the vials here you got to save it of
course exit boot back into Windows okay so an impressive result here I've got 83
frames per second and a very easy half life lost coast video stress test you
can get this off steam by the way for free to try and compare the results here
so max temperatures about 58 60 degrees is what it's going to reach at the
moment the longer you play the hotter it's going to get but the same exact
test when I did it with 18 watt power limit with no copper heatsink mod it
reached 93 degrees so you can see there that the difference is absolutely
massive when you do these mods and you unlock the power limit you can almost
double the framerate well not quite double because before I got about 58
frames per second and now it is about 83 almost 84 and they're looking at the
difference it's made with a game this is Counter Strike global Offensive that
when I tested this in my review was getting about 30 frames per second and
now we're up about and did already up about 20 frames per second temperatures
are reaching however 70 degrees so it's still getting a little warm but this is
so much cooler than having this stock if this was stock it would be running as a
thermal throttling 99 degrees now without the copper heatsink mod and no
power limit of course so thank you so much for watching this copper heatsink mod
the Teclast F7 Plus bye for now
