Advice on high CPU temperatures when Chromecasting a tab with video

[marius7777]

Hi.
Usure if anyone here has experience with casting tabs through Chromecast, but the I noticed that the temperature can get pretty hot (average 80+ degrees C, sometimes with peaks of 90+) when I cast a tab with an Amazon Prime video stream.
Is this very bad?

When nothing playing/casting I get ~35-40C. Casting a Chromecast-enabled website like YouTube (that stops the player and sends only the stream to the TV) : around 51C.


Laptop is ASUS N750JK with Intel i7 4700HQ (Haswell), 2.5 years old.
Someone recommended that disabling Turbo mode will help. Should I?

Clean dust off heatsink and repaste / Service laptop
Invest in a Laptop Cooler
Make sure you using laptop on a flat surface and not on a bed or something

I'm using it only on a desk. Indeed, it wasn't dusted or repasted until now and I plan to do that today.

I was thinking about a cooler pad or smth similar. By laptop cooler you mean something internal but a better model, or something external? I'd buy that especially for hot summer days

The only time I've had anything similar happen my heatsink fan was on its way out..... But it got hot like that with everything.

I noticed issues only when casting the tab. 50-60C at most during streaming or other intensive tasks. The laptop it's not that old, so I hope the fan is still good

So I just opened it to clean it and it was fairy clean, no dust on the fans, only on the vents a bit.
I'll do some more tests with casting, and also with Turbo Boost disabled by setting 99% in Power Management

its a stand were you sit the laptop and some fans will push fresh air inside vents, helping your internal cooling to improve.....

Great, using laptops over beds, clothes and other irregular surfaces that might trap heat, so get yourself a cooler pad like the photo ...
replacing thermal paste, cleaning out the computer cooler and vents might be a dedicated task, beware if you are not able to do it yourself, or have some doubts about the process... or lack of knowledge, better take to a repair CP shop... seems easy but it requires attention, skills and knowledge... so be patient if decided to give the shoot by yourself,

you just need:
Thermal interface material: Arctic MX4, recommended!
Coffee filter: they are lint free, excellent for taking old paste out, use'em as tissues,
Isopropyl alcohol: for cleaning, disolves old paste easier!
Plastic brush: need no explanation right!
precision screwdrivers: little screws are easy to destroy when not using the correct tools, beware with all laptop screws,

Tons of patience are also needed, if first time, try to look youtube.com for videos of the same task your are gonna do, example, Toshiba ultra bool model: XXXX repaste, thermal paste renoval, etc

With Turbo Boost disabled, I get now around 65 degrees with streaming + casting. Very rarely over 70 (if I do something else at the same time).
I also bought a cooler (DeepCool N8), but it's not making much of a difference (same average temp with it turned on).

did you at least cleaned the laptop? thermal paste replaced? vents checked and cleaned?

Yes, I cleaned it, checked it. Didn't need much.
No thermal paste replaced, because I asked some people and, for a 2.5y old laptop which I haven't touched inside, they didn't recommend replacing that.
Is it necessary in this case? Asking because that I wouldn't be able to do myself.
Others mentioned it could be some problem with the internal cooler. Don't know how to check that other than buy a new one.
Also for regular use I get fine temperatures (e.g. now with browsing 37-39)

better take that computer to a repair shop...

" for a 2.5y old laptop which I haven't touched inside,

Hmmm , to clean the vents you wound normally need to strip and remove the heatsink then require new thermal paste anyway
Did you just clean the vents from the outside? as that would not do much as the vents get blocked from the inside of the heatsink
With a laptop cooler you should have lower max temps at least

You may also be able to set the Display setting to Perfermace and not Quality for your broadcast software- under your gpu display settings

Why are these temps a problem???

This is more than fine for a laptop CPU, they can go up to 90 C no sweat.
