Predator Helios 300 PH315-53-72T7 Are temperatures, fan speeds, etc normal ?

Hello,

I have an Predator Helios 300 PH315-53-72T7. Specs, basically are, in short:

1.- i7-10750H.

2.- RTX3060.

3.- Came with 16 Gb RAM, I expanded to 16x2 = 32 GB of DDR4 3200MHz (CL22).

4.- 1 Tb NVMe SSD.

Running Quake II RTX free version, that uses all RTX graphics card capacity (or at least heavy duty so to speak), I got these numbers below in the picture from Predator Sense application:

I have some questions:

1.- I think in the plateau, when I was playing, temperatures are normal, do you guys agree?

2.- As expected, temperatures ramp up and down in an exponential basis, , but after a while, when I closed the Quake and stopped killing folks, just working with email, office, listening to youtube videos in the background, is it normal to to have the graphics card at 51 º and tis fan at almost 3500 rpm?

3.- Why the hell is processor at 66 ª after a while (I mean 15 min or so)?

4.- Are max temperatures within normal?

5.- When should I add thermal paste to chips?

Again, thanks a lot in advance for your priceless insight!

Best Regards

Here's my free insight. 🙂

Yes.
Yes if CoolBoost is enabled
Temps drift up if you keep running videos in the background. Some videos or video frames more than others.
Anything below 86*C for the GPU is normal under heavy loads.
Annually if used mostly for gaming

Thanks mate. The laptop is one year old, but gaming or rather raytracing apps from work that use all threads of GPU so load it to maximum that I run here, they don't take more than 5 % of the total use of the laptop, may be changing it every 2 years is ok? Btw, do you recommend those cooling bases where you place the laptop on? Do they help? I believe they expel air upwards, and I think laptop sucks air from below to back and side grids, is that correct?

Again, thanks for your time!

Should be OK till you start seeing GPU temps hover near 86*C red line. Main intake & exhaust vents are on the bottom sides. So raising the laptop about an inch above a hard surface without blocking vents promotes air flow. Coolers usually not needed.

Thanks, problem is that GPU at full usage goes above 86 ºC, CPU if loaded goes also higher, but rather transiently. Thanks for the pic, I already saw, my question was more how is the airflow, is the grid shown in the pic sucking only?

Thanks and Regards

Intake sucking is mainly over the fan blades on the right & left vents. Exhaust blowing is mainly over the processors in the middle vents.

Strange, "wind" comes out mainly from the side on the right, also from the side on the left but less...

JackE

You can't tell which way the wind is blowing unless you actually feel the intake & exhaust vents. They're on the bottom. Don't block them.

Strange, there should be like a route for the air. As far as I know all cooling bases expel air upwards to the base of the laptop, so I presume the base grids will always suck...

Thanks!

>>>all cooling bases expel air upwards to the base>>>

A laptop is not a cooling base. The fans suck air in at the laptop's bottom intake vents. Then blows the air through ducts to the CPU & GPU heatsinks. Which then escapes downward at the laptop's bottom exhaust vents.

I never said a laptop is a cooling base, Obviously the fans suck air from outside to heatsinks as you said. My question was about the direction airflow. As far as I know, correct me if I'm wrong, any typical commercial cooling base for laptop, expels air upwards, which would help cooling the laptop if the laptop sucks air from the bottom, otherwise wouldn't help. My doubt was if laptop itself sucks air from the base, which I think is the case, but obviously I'm not sure, that's why I was asking if somebody knows what is the airflow direction in the laptop...

Sorry, it was my mistake, I wanted to say: "all cooling bases expel air upwards to the laptop (not base, obviously)"....

JackE

A laptop on top of a cooler that blows air into the laptop's intake & exhaust vents, impedes laptop airflow. Accordingly, I don't recommend coolers. Raising a laptop about an inch above a hard surface, promotes laptop airflow.

Actually you are not the first one from whom I hear that opinion. I will try to rise it 2 cm or so and see how it goes... Thanks again from your time.

JackE

Good luck. Make sure the none of the air vents are blocked whatever you use to raise the laptop. Mine sits on a roasting rack from a toaster oven. Lowers peak temps by almost 10*C

Thanks, I rose the laptop 2 cm higher with 4 small wooden pieces to try, I run the same game for some time to reproduce the conditions and what I saw is that max temperatures were a few degrees lower, during playing time yes, few degrees lower, when no loading with heavy duty game, temperature almost the same, I would say that fan speeds with laptop higher were something like ~300 rpm less, which makes sense as you don't have to force the air that much, but to be honest I don't see a great difference after all:

JackE

Do you have CoolBoost enabled?

Not actually, what is that for exactly?

JackE

Usually increases fan speeds. It should be an option in PredatorSense or QuickAccess. Some folks have reported problems accessing it in this link. https://community.acer.com/en/discussion/663493/coolboost-option-missing-in-predator-sense-helios-300/p2

Yep, I tried it and first thing is hearing fans speeding up, but at the end, still not much difference, temperatures kind of the same, I will just keep it a bit higher and I hope should be enough... Thanks!
