Does that temperature is danger for computer?

[Pawelk198604]

Recently the temp display on my computer changed color from blue to read, and get beep sound warning does that temp are bad? In Poland we have 39 C outside we have heat wave but does is the reason to not use computer?

But now i'm going to to pool

39 is nowhere near dangerous for a computer. Even twice that isn't.

38.9 isn't too hot for a PC, so long as the cooling systems are working. Dust traps heat in computer components; so it would be a good idea to open your PC and blow all the dust off everything. Then find out how to set the heat alarm so it warns you at a higher temperature than 38.9C!

Enjoy the heat while it lasts!

Mine used to be 89-90 C until I fixed the damn cooler fan and even after those temps my CPU survived as good as before so don't worry

No. Air temperature doesn't matter. What matters is the core temperature of the CPU and GPU. High temperatures can decrease their lifetime. I have a rule of thumb for this:

60°C or less: Normal desktop use, light/medium gaming. Safe to run 24/7.

60°C to 90°C: Heavy gaming and other very resource intensive things. Safe as long as you don't run it 24/7 - 12 hours or less should be just fine.

90°C to 100°C: This should only happen during stress tests and never during normal use! Only safe for short periods at once - an hour or two at most!

100°C or more: Not safe - shut it down immediately! Identify the malfunctioning component and repair or replace it. If it looks like a software problem and you can't identify the cause, reset the BIOS and do a full reinstall.

GPU tend to run close to 90 degrees, had one where the fan stopped working and it shut down at 110.

This. Air temperature says almost nothing about your hardware temperature.

60°C or less: Normal desktop use, light/medium gaming. Safe to run 24/7.

60°C to 90°C: Heavy gaming and other very resource intensive things. Safe as long as you don't run it 24/7 - 12 hours or less should be just fine.

This is a bit on the enthusiastic side. Most modern (desktop) processors have a maximum recommended temperature of somewhere around 60-70 degrees Celsius. Anything beyond that is becoming dangerous, and also important, you likely lose performance due to thermal throttling. The chips tries to protect itself by cutting calculations and lowering temperature that way.

I would say anything over 80 degrees Celsius is reason to either reduce workload or increase cooling. Though that is a terribly rough generalisation. It really depends on the chip.

GPU tend to run close to 90 degrees, had one where the fan stopped working and it shut down at 110.

GPU's can generally take more of a beating, though they have their limits. CPU's are much more sensitive to temperature.

a good fan is a really good investment, especially if you have a good CPU. Replacing the stock ventirad with, say, even a 20$ fan can double the lifespan of your CPU, wich is a huge gain of time and money considering a CPU is worth at least like 200$...I have a middle-end 25€ fan for a good i5 CPU and my temps are always under 50°C, and go as low as 30 when idle...39C outside temp does not matter... try to install a program that will tell you the actual temperature of your components !

Yes especially if the room temperature is high. Current pc has 3 inn fans and two out fans, this generates an over pressure who is nice to keep dust out, out fans also cools the radiator.

One think to watch is hard drives, no they have no issues with 50 degree, however loosing one can be bad even if you have backup it takes a one day to get an pc up and running at task specified behavior. 2-3 days for all software weeks for all the games and minor settings.

I once vacuumed out a dusty powersupply, I turned it back on and a capacitor immediately blew up.

Vacuum cleaners can be extremely good generators of static electricity. I'd never let one near the innards of my pc.

Compressed air cans are my preferred solution for things like that.

I fixed overheating problems during the summer heatwave by pulling off the side panel and running a small desk fan to remove the excess heat.

Get SpeedFan. You will get to see the actual temperature reported by the sensors on each of your hardware. That way you get more accurate results.

It also has fan speed control feature and several other things, but the heat monitoring feature is really useful.
