A Note On Heat

[boleyd]

Maximum heat seems to occur when editing in TRS2022 and changing landscapes - elevation and texture.
The improving graphics take a toll on processing and elevate temperatures.
I use TRS2019 for editing and TRS2022 for watching. I believe the risk of loosing a PC is not worth the features of the TRS2022 editor.
With global warming it will only become more critical.

Maybe we will become nocturnal - sleep during the day, trainz at night.

Earth's average surface air temperature has increased almost 1.5 °C (about 2.5 °F) since the Industrial Revolution in 1835: https://en.wikipedia.org/wiki/Climate_change

If PC was designed even during the Industrial Revolution, then 1.5 °C still not affect anything anyway.

I checked and on TRS2019, my PC was using 100% of its CPU at 3.39GHz when its base speed is 2.90GHz

If you do not want strong heating, turn on the V-Sync in the launcher settings. If the heating does not decrease significantly, turn on V-Sync - half.
Without V-Sync enabled, any, even the most top-end hardware will always be loaded at 100%.
V-Sync limits the FPS to the value required by your monitor and set in the monitor specification and hardware does not generate unnecessary frames.

That's a good thing. It means that TRS19 is using your CPU as it should. If the usage was at 100% all the time I would worry.

I forgot to mention that the base speed is a publicity stunt and the CPU in practice never works at this speed.
My CPU has base 3.30GHz, 3.90GHz turbo, 800 MHz idle, but even with minimal load, it immediately switches from 800 MHz idle to 3.90GHz turbo and it normal for any CPU.
If you really want to reduce CPU speed to the base point, if you have enough performance and don't need extra heating, you can only turn off CPU turbo mode in the BIOS (UEFI).

When cleaning out any accumulated dust from the inside of internal pc cases one uses a small size vacuum cleaner with an accessory brush on the flexible hose pipe.
Suck out the dust it instead of blowing out the dust, less chances of damage to components.
The dust then goes into a dust bag or an HEPA filter in the vacuum cleaner.

Make sure the vacuum is safe around electronics and the mains plug as well as the vacuum hose is grounded otherwise static build up can occur and zap the components. I have a special vacuum/blower made specifically for electronics. I purchased this more than 30 years ago to clean out a Varityper Epics 20/20 typesetting system, and is the same model that I used in the computer room at work to clean the DEC LP27 band printers and the VAX 11/780s.

This is a re-post of a post I made in a private gaming FB group I belong to:

"This is a post to help the group in general, re: caring for their computers

I bought a compressed air duster for cleaning my computer today.
I'd been using the canned dusters for a few years, but the cans are getting really expensive at 22 bucks for 4, and then there's the need to dispose of the cans later.

After perusing many different suppliers, Amazon, MicroCenter ect. I decided to go with a duel purpose compressed air duster by XPOWER, for 54 USD. There are cheaper dusters that sell for 25-30 USD available, but are all very cheaply built and have horrid QC, so you'll have dead batteries, shoddy chargers, fan motors quitting, and more.

I read reddit threads on the topic and the top unit was a datavac canister, used in electronics shops and computer service centers, and XPOWER units.
The datavacs sell for 150 ish USD and are large units, while the XPOWER sell at 54-60 and are useable BOTH as outdoor blowers, vent blowers AND computer/electonics dusters.
Here is the link for anyone considering one for themselves.

This one is a redesign from the previous S2 model. "

Where I live in the northeast US we get really hot and humid days in the summer and heat waves. We don't have AC in our house, just fans and I have a little square Arctic Air by my computer table to keep me cool. I should get a few more of those. The upstairs gets really humid vs. the downstairs and you can feel it on your skin because on high dew point days you can't sweat right because there is too much water vapor in the air and it sticks to your skin creating the uncomfortable sticky skin feeling. Normally your sweat evaporates keeping you cool, but when it is humid it can't evaporate because the air is saturated with water vapor so it stays on your skin. You feel hot, clammy and yucky. Climate change is causing hotter summers.

The same for us a bit farther north in Southern New England. The 86% - plus humidity along with 90 F degrees or more create awful sultry conditions. I only have one window air conditioner and I use that in the room where my grand piano is located so I can sit in the room and play. I would set up another small window unit if I could but I don't have enough outlets in my room to do that, so the room with my computer has every window open plus a ceiling fan and a box fan running to keep things comfortable not only for me but also for my computer.

The other big concern in the hot weather is low power. With everyone and their uncle running AC units, this puts a big load on the power grid. I noticed on my UPS power meter during warm days that the line voltage drops from 119-120V down to 114V or lower. This higher power drawn by the computer equipment pushes the power supplies and other components harder causing even more heat and can lead to failed components.

Drastically reduced my system's heat output and increased performance going from i7 4790K to i5 12400F. Most amazing thing is the CPU cooler was Noctua NDH-15 before, now using the stock Intel. Same computer case.

I ran TS2019 yesterday with a room temperature of 77F. The CPU temperature monitor showed 94C as the top number in the afternoon. I switched to TRS2022 and it hit 100C cutoff several times. All those "deluxe" graphics calculations (3 dimensional ) eat CPU cycles.

Looks like the specifications listed on your signature shows a space heater with high end CPU and GPU parts. What kind of chassis (computer case) is this living in?

 

[HPL]

However, you need to make sure that you keep any fans from spinning! The compressed air can and will spin the fans WAY too fast.

The fan would act as a dynamo in this case and the electric power produced may damage the motherboard.

I have a very small case (I wanted it with the upper location of PSU), slightly redesigned.
The side ventilation openings have been sealed, and the filter has been completely removed from the front lower grille.
100% load - i5 6600 - 50-55 C, GTX 1060 6GB - 72-75 C.

Does the computer sit on top of a desk, under the desk, next to it on the floor or something else?

The computer is on the floor, under an ordinary table with four legs.

The only real effective way to reduce heat on the CPU/GPU is by going liquid cooling. I've been doing custom loops for 20 years as air cooling can only do so much based on ambient temperature. I have my 13700K and RTX 4080 both on a custom water cooling loop and other than occasional spikes when the CPU is under 100% load its nowhere near thermal throttling.

Get it off of the floor.....all it is doing there is acting like a vacuum cleaner and sucking dirt in.

doesn't matter where you put it, it will still suck the dirt in...
