CPU Temperature - Real Temp

About a year ago I was having an issue with very high temperature for my CPU. I found out my CPU fan was 'off balance' to make the long story short so part of it wasn't being touched. Anyway, someone recommended RealTemp to monitor the temperature and I still use it to check here and there even though I no longer have the problem since I got a working CPU fan.

I noticed when I'm in my BIOS and it states the CPU temp when I restart the computer or even first turn it on, that it says it's at 71 Celsius, which seems high for not really doing anything, but Real Temp states that it idles at about 58-60 degrees.

Is one more accurate than the other? If the BIOS is more accurate and it idles at 71 then it'd be getting pretty hot for whenever I play any games.

Thank you

Usually the bios is more accurate then any temp software

"but Real Temp states that it idles at about 58-60 "

Even those are kinda high. I think you might have a problem.

I like my idle temps south of 40 C but idle temps are affected by ambient temps so what you your room temperature?

In the bios the cpu runs at full speed.
In windows Speed step or Cool and quiet are activated and the cpu speed and voltage is reduced when the cpu is idle.
So both temperatures are probable accurate unless you have the features disabled.

My room temp is probably mid to high 70's (F). Not sure what that is in Celsius, like 26-27ish?

And as someone else stated I do agree it is still pretty high for idling. The case is well ventilated, but maybe my stock CPU fan is just insufficient. Anyone have one a couple they recommend, I've never looked to deep into them. My CPU is a Intel 2500k Sandy Bridge and the mobo is a Gigabyte Z68MA, but I'm going to be switching it out shortly for a micro ATX mobo for a micro case I bought. I'm guessing that may limit to what CPU fans I can use?

Thanks everyone.

Also I've been checking the temp from BIOS a lot in the past 2 days because I've had this really strange problem where my computer now refuses to ever stay in sleep mode, and I've been trying to change a few options under Power Management and a few other sections of BIOS to solve this (still can't). Anyway, the BIOS says it's idling mid 64-66ish average now. I'm guessing it's lower because I just cleaned all the hardware of dust and moved my case so I think the fans get a little better airflow for drawing in cool air.

I still could probably use a better CPU fan though.

"idling mid 64-66ish average now"

Yikes that is hot for BIOS idle. I think there is something else going on. When you installed the cooler how much thermal grease did you use and what kinds? How did you clean your CPU and Heat sink? Is you heat sink fan making unusual noise like it may have a bad bearing?

No, it's not making any strange noises. I've had this build for roughly three years and since it was my first build my friend helped me with putting it together since he's done several. I've heard putting too much thermal grease actually hinders it somehow, but I think he put an adequate amount on, but I do remember that he didn't spread it over the entire surface area, and just a large central portion. I've been doing some digging around and a lot of people seem to have the opinion that stock Intel CPU fans are just very sub-par. On top of that maybe mine has some default, or the thermal grease was applied incorrectly. How much should be used?

I didn't clean the CPU itself, I just cleaned the heat sink by using a compressed air canister to try to blow any dust out and then took a very slightly damp cloth and went over what areas I could.

The stock heat sink already has thermal paste applied to the mating surface.
If your friend applied paste to the CPU along with the paste on the heat sink base you have an excess of thermal paste.
