CPU & GPU temperatures - Should I be worried ?

While playing games, my CPU is at about 60-66ºC, GPU at about 75-85ºC.

idle temps isn't normal

CPU idle temps are too high, load temps are fine. So no, there is no need to do something about it, however cooler temperatures are desirable.

What cooling are you using?

The problem with your idle temp is that your CPU was not idle, it was around 25% usage, so you can't really call that an idle temp. My CPU bounces between 0 and 1% when my computer is idle.

I would think 60 degrees is a little hot for 25% usage, but i'm not 100% sure. What you need to do is run a stress test program like Prime95. It's a small, free, easy to use program that will keep your CPU at 100% load so you can see what temps you will get under full load. Your full load temps are what is important.

You have a 2500k CPU. You should look up the throttle and max safe temps and see what other people say. These numbers will be different for different CPU's, so you need to specifically look up numbers for the 2500k. Don't just take 1 persons answer and think he is right, this is a personal preference. Read some posts about what temps other people get based on if they are at stock or overclocked speeds and have stock or aftermarket cooling and then decide for yourself what temp you want to run.

Running higher temps will shorten the life of the CPU, but even while running higher temps, you will probably get rid of the computer many years before you run into any problems. Some people like to stay below 70 degrees at full load and some people like to stay below 90, it's all personal preference. If you stay below 70, you should never have to worry about problems related to heat.

Do the same thing with the GPU. Look up the model and safe temps and decide for yourself. GPU's usually run a little hotter than CPU's.

If you find your temps are higher than you like, there a a few things you can do. First, make sure the computer isn't full of dust. Pull the side panel off and vacuum out the dust from the inside, making sure to not break anything and be careful about static electricity, especially if on a rug. I usually do this once a month.

2nd, If you only have 1 fan in the rear of the case pulling air out, I would suggest getting 2 more 120mm fans (at least 1) and putting them on the inside of the front of the case to pull air in. Your case already has holes there to screw them in.

3rd, If temps are still too high, you may need to re-apply new thermal compound between your CPU and cooler. Look up instructions on how to properly remove and install your cooler and apply the thermal compound if you don't already know how.

4th, For even better temps, purchase a new aftermarket cooler. A larger cooler will remove more heat. Make sure the new cooler fits in your case though. I think your case can fit up to a 160mm tall cooler based on what other people say, but i'm not 100% sure. I don't think there are many aftermarket coolers over 160mm, so most should fit.

You have a 2500k which is an overclockable CPU. If you get an aftermarket cooler, you can easily and safely overclock the CPU to make it run faster than stock. Modern CPU's are extremely easy to overclock, but definitely do some research first if you don't know what you are doing.

According to CPUID, your CPU & GPU temp is OK in idle mode !

I wish I could help but I don't understand celsius.

They are fine especially with a stock cooler.

Gpu: ok
CPU: a lil high in idle but that's ok

Less that 70 won't explode anything. Don't worry yet.

Lot of people replied already.
So i will only say this irrelevant You have good tastes in games :)

They're normal, but you should clean your case and change your CPU's thermal paste just in case to lower those temps by 5-15 ºC

Air cooling normal temps for desktop PC:

CPU
Idle: 25°C - 40°C
Max load: 45°C - 55°C

GPU
Idle: 30°C - 40°C
Max load: 55°C - 65°C

Liquid cooling normal temps for desktop PC:

CPU
Idle: 20°C - 25°C
Max load: 30°C - 45°C

GPU
Idle: 25°C - 35°C
Max load: 40°C - 50°C

...anything higher than that is not normal! And yes you should be concerned. The best thing for a PC would be always constant temperature while idle/full-load. The thing is if temperature difference is huge between PC turned off and at full load the material streches too much and if you are doing that everyday (turning it off / playing it) after a year or so or maybe up to two years there will be micro fractures somewhere on the mainboard/GPU power planes/wire traces near transistors or capacitors and your component will be "dead".

-Stock fans are usually not good enough (maybe they are for office work but not for playing games) and most of the times factory applied thermal paste is not applied properly (too much/too little). There is also a difference in quality of thermal paste. The very cheapest ones are usually plain shit.
