CPU & GPU temperatures - Should I be worried ?

Your idle temps are uninteresting, but the temps whilst playing are ok, no need to worry if they aren´t increasing.

I can suppose u are using the stock cpu cooler

You must do something (clean insides of your PC, change thermal compound on cpu and gpu, change whole cpu cooler for a better one, if you have old computer case then you could change it for one with better air flow). There are many possibilities why your temperatures are so high.

100-110 ( ur fried ))

90-100 (ok)

80-90 (good)

70-80(verygood)

60-70(excellent)

Edit: Here i found a good article about preventing overheating. Mybe will help you.

If you have a stock cpu cooler it's quite normal.
You could buy a cheap cpu custom cooler and get at least -10°

idle temps are a bit high, try to clean your case

It's a bit high but nothing to be seriously worried about unless you are getting performance issues. Cleaning your heatsinks and the rest of the case might help. If you don't have case fans, you might just want to leave your case open.

//edit: My temps on my laptop, but it doesn't seem to read my GPU temp. (not idle, but im not gaming or running other heavy duty applications atm either)

Playing Wasteland 2 and it took me a while to figure out that noise. It was the GPU fan spinning at higher speeds.

You can always see if you can manually adjust the fan speed for your GPU. I never feel like it kicks up enough, so I turn the GPU fan up using the AMD Control Center when I'm gaming, to help keep things cool. Also, buying an after-market CPU cooler makes a world of difference, especially if you do any overclocking. Having adequate case fans is also really important.

They're fine. You can drop them with few degrees with proper air flow and a lot more with an aftermarket cooler if you're still using the stock one.

You are probably just overdue on dust cleaning.

what you can do, put a fan directly on the PC (hope it's not a laptop). it's kind if an insta fix. open the case for better results.
but be careful of dust accumulation

Idle cpu usage should be ~3-5%, not 25 so better check what's eating up CPU

You say nothing about room temperature, it's the difference not absolute values that says about efficiency of air cooling.
To have comparison: at 23C ambient and idling, my i7 is 33C, gtx970 is 40C, all hdds at 32-36C. All in noise (and airflow) restricted case with fans spinning at 500-750 rpms

You shouldn't be worrying until it gets over 75-80C, if you're running a PC.

On a laptop, the extremes of 75-80C can be often when stressing the machine.

Once you start reaching 90-100C your processor may slowly degrade depending on the quality. Most machines will automatically turn off if you reach these limits -- but they can be disabled.

Don't worry, your processors won't literally start "frying" until over 120C, and buffed up machines with huge heatsinks/fans more near 200C.

Dont worry, a bit high but thats OK. You can use MSI afterburner, is better than Speedfan.

A bit high? For real? Hell, these are absoltely fine temps! Everyone who says otherwise has either never really surveyed the temperatures while gaming, uses watercooling (and i mean real watercooling, not that pseudo-corsair-crap) or reads the sensors wrong. 78 degrees worrisome, my ass...

The only time you should worry is when you overclocked to the max and hit 70C°

I fail to understand idle temperatures with that software (I use hwmonitor / cpu-z / gpu-z), but as long as cpu is under 60 and gpu is under 80 under load, you are fine. You should however keep an eye on that HDD temperature.

They seem like they're on the slightly higher side to me. Room temp can make a hell of a difference though.

What's using up your CPU like that? I have an i5-3450 myself and it hovers between 0% and 3% whilst idle. Also, if you're still using the stock Intel cooler, a great investment (imo) would be an aftermarket cooler such as the Cooler Master Hyper 212 EVO - have one myself using a push-pull config (added an extra fan), and can vouch for its awesomeness - funds permitting, of course. I forget what it used to idle at with the stock cooler, but now it idles at 35°C.

Regarding the GPU, is it a reference one? Or perhaps an ASUS, MSI, GIGABYTE one? Reference GPUs don't usually have the best cooling solutions. You could also set a custom fan profile using a program such as MSI Afterburner. My GPU used to idle at around 55°C - 60°C until I set one, and now it idles at 34°C.

As mentioned above, you could ensure it's as dust-free as possible, and ensure your cable management is as neat as you can get it - the latter making a tiny bit of difference, but helpful nonetheless. If your case has any free fan slots available, you could utilize those (again, funds permitting).

Lastly, if your case doesn't already have dust filters covering the intake vents/grills, I recommend those too - they really do work, but you still have to clean them every now and again.

I forgot to point out, overall though, I wouldn't worry about those temps.

Edit: You answered some of my questions already. :)

This is by my opinion way too high. I have cooler master HAF922, and Phenom x4 with GTX770 asus dcu2 gpu.
I have 18c temperature of cpu when idle, and 35 of gpu when idle.
On full load i have 45-50 of cpu and MAX 72 of gpu.
This is also high for me so im planing to add 1x 200 mm fan on side of the case.
I think you should replace termal paste on cpu/gpu, change computer case, and make air flow through case, and its really important!

They're serviceable, but the lifespan of your CPU and GPU will be lowered. Consider opening up your case and de-dusting, and giving your heatsink and GPU fans a blow-through. If you're cool with removing your motherboard (or if you have a modern case that allows you access to the underside of the motherboard), I would really suggest investing in a Hyper 212 heatsink. They're cheap and far more effective than a stock heatsink, but require you to attach a small panel to the underside of the mobo. Also, some good ceramic (non conductive) thermal paste applied in the correct 'pea style' method on a cleaned CPU top can make all the difference.

I mean, ambient temperatures play a big part. In the middle of summer when the air is humid as hell, the computer can only cool itself with that air, but a non-stock thermal paste and heatsink makes all the difference. That, and making sure you haven't accumulated any dust bunnies in your case, heh~

I have the same CPU and temps @idle are ~29C

That would have been a great place to hide a giveaway! Add a five letter code under 3Vsb and hardly anyone would notice :D

Like many have already said, your temperatures are OK, but not optimal. You haven't said anything about what CPU cooler you are using (the stock one that came with the CPU I presume?) or anything about your computer case. There's perhaps a lot you can do to improve on the cooling, but I wouldn't panic over those numbers.

View attached image.

cpu:
Max Temp inside your Case for the i5 2500k CPU is according to intel 72°C ... which means the temp of the CPU can easily reach
80 to 90°C which is still fine (except for the unbearable noise i'd imagine with stock coolers).

gpu:
AMD GPUs are quite the hotheads ... anything below 90°C is fine. You could further reduce your temp (increase the FAN RPM) with this:
Totally safe and easy to use with almost any AMD Card: https://www.sapphireselectclub.com/ssc/TriXX_de/
^ Used it a while ago myself to reduce the RPM and have the fans more silent ...

Oh and btw. if the temp of the CPU / GPU ever reaches its limits, it throttles automatically and if its unable to reduce the temp >
it shuts down the system before it even gets a chance to be fried ...

maybe for the cpu while playing but the gpu can handle 90 easily

That is rather Cause for Concern, Those Temps are above normal. Everyone obviously has there own opinion. but Operating at that temperatures is not good. I see you mentioned Stock Cooler. I would personally try to invest in a better aftermarket cooler for both the CPU and GPU.

if you saw my CPU cooler which weighs 1 kilo by it self. with Idle Temps 7c, Max Load, 22c. and my GPU is Artic Cooler. Idle. 29c Max load 45-50c, Never ever gone above 50c in hardcore games.

recommend trying to at least do something to fix that high temps. anything close to 60c, whether its CPU or GPU is my book is the max it should ever go, higher is cause for major concern.

Edit: If you really can't invest in anything, id suggest putting those fans on max during gaming. Had a look at the case, it's decent, hope the airflow in there is good. i have a custom built pc case made from pine wood which i used a blow torch on to make the texture abstract and contour lines stand out, then used wood varnish to add the finishing touch, it looks like a dragon breathed fire over my case. and nope. no heat issue. you must be a newbie pc builder if you think wood causes heat issues.
