Is 40c for an idle cpu considered a high temp?

[Ntinos]

Hi! Yesterday I finished building my first pc and when it took me to BIOS the cpu temp was around 38-43c. The room had about 30c and I also had the side panels removed. I have an i5-4460 3.2ghz cpu and a hyper t4 cpu cooler. Should I be worried? Im 80% sure that I applied the thermal paste exactly as shown in the videos. Should I save money for an h100i cooler? I think the motherboard temperature was about 25c(or 35c, I cant remember but I think it was 25c)Thanks!

No, that is a pretty good temperature. 38C is about the lowest you will normally see on a CPU running Windows (due to background tasks). A 100% load temperature in the low 60s C is also good. If the CPU temperature gets too high (over 72C) it is running too hot.

My I7 4790k with hyper 212 evo had 32ºC on idle... Now with the Corsair H110I GTX the idle tems are same... You dont need to buy an H100i for those temps.

Well i have fx6300 at 4.5ghz with the same cooler and for me it idles at around 30c. But your ambient temperature is very high, so thats about right. I wouldnt really worry about idle temperatures. Temps under load is what have to be kept eye on.

Try using a program like realtemp and monitor the idle temps in windows. Usually temps are higher in the bios because the cpu isn't allowed to throttle down using speedstep the way it does in windows. You should be ok, the t4 is better than the stock cooler and the 4460 being a locked cpu won't be running hotter like an overclocked cpu. It makes some sense though with room temps around 30c, that's pretty warm and 'common' ambient room temps used by testing sites and things are closer to 22c.

More important are the load temps. You can leave realtemp open in the taskbar and go on about using the pc like normal whether browsing, watching videos, gaming etc. It shows the current temp and records the lowest and highest temps the cpu has been at since the program was opened until you close it.

Here's an idea of what temps should be at load.

I have i7-4790k with hyper 212 evo and 29C idle. It depends on voltage, that's up to around 1.27V.
