Hey guys another one of these questions, I've been reading up on some threads, but wanted some feed back more specific to my setup.

I have my i5-750 quad processor overclocked to 3.4ghz right now and it's running stable but I worry about the idle temps.

Cpu is running at stock voltage.

I also have a COOLER MASTER Hyper 212+ and a NZXT Mid tower, Raedon 5850, 2x2gb jiggsaws 1600, 650w corsair psu, wd 640gb 7200 hd, GIGABYTE GA-P55-UD5 LGA 1156.

My cpu idle temps range from 34c-39c depending on room temps.

My load temps with prime95 test for 6 hours didn't hit much over 60c. Everything was stable.

So I was just wondering, should i be worried about idle temps around 34-39c when my load temps look good (right now it's idling 35-38c)? Is it going to effect my processor in any harmful way?

Thanks
Matt

Always best to use Aftermarket Thermal Grease like Arctic Silver 5, ARCTIC COOLING MX-2 or OCZ frezze
But make sure if you do replaced it, to view this video http://www.youtube.com/watch?v=o7rPqCvCt0g
make sure you spread the compound until there is not air pockets. (Only a grain of rice amount...

your temps are fine for your Lynnfield CPU
The max temp before OCing becomes useless is around 90 degrees.
Staying around 60c is a good temperature for your CPU.

Overclocking your CPU will always decrease its life span. From what i can find out, its by a few years (on a CPU rated to last many years past its relevance) and most people get rid of it by then, since its obsolete long before it will physically expire.

Well No and Yes, Mine CPU is Clock at 4.0GHZ but I am going to set it to 3.8GHz for you to show the temps .
Now as you see that I also have Intel i5 750 Quad Core and my idle temps are
Core#0 - 33
Core#1 - 29
Core#2 - 32
Core#3 - 31

Full load they are at
Core#0 - 55
Core#1 - 51
Core#2 - 52
Core#3 - 56

Reason why they are at good temps are my voltages settings.
Well I believe that if you can adjust the voltage just a little and not on (Auto)
You should be seeing better idle temps. You have a excellent heatsink there but question is
what type of thermal grease did you use? How did you apply the thermal grease to the CPU?
That counts at well. Here is a photo of the set up that I set up for you on my Intel i5 750 to prove to you that
temps should be a little lower.

Thanks for the replies guys, it's very helpful.

Hmmm i just used the thermal grease that came with it. It was my first time applying it, i just put a bit on, and spread it around.

Maybe i should by a better quality grease? then wipe it down and reapply? What are your thoughts? I'd rather not mess with it becuase it was a pain(i'll get used to it i'm sure), but if it's going to lower my temps a few degrees i suppose its worth it.

Make sure you are wearing plastic gloves and you can to it with your fingers or a credit card shape or business card

n Just little Up photo. If you leave you PC at idle for a long time you should see temps like this (note only if you do have excellent cooling)

nYou can see the temps on minimum (idle)
nCore#0 - 30
nCore#1 - 25
nCore#2 - 28
nCore#3 - 26
n
nMaximum (Full Load)
nCore#0 - 57
nCore#1 - 51
nCore#2 - 52
nCore#3 - 58

nThat is because I was gaming for 6 hour straight ( :D )

^ Nice temps, What are your ambient temps.

Only reason for my post is that there can be 10 Degrees in ambient temps between 2 posters - ie US vs "Down Under", or Numb Nuts Alaska (Burr) and Miami Florida - Then their are the ones that like it HOT and ones who prefer the cold.

Food for thought. When asking about temps it would be niece to know what ambient temps are. I have a indoor/outdoor Temp. I have the outdoor bead placed about two inches behind the HSF intake (generally about 2 -> 3 degress higher than room temp ( can tell when I need to clean the filters), and a good indication of good case flow.
I can tell when the heat clicks on (Winter) and when A/C is on in the summer. The floor vent is about a meter away and in the winter I defect the air away from the computers and in the summer direct it toward the desk.

My temps are on avg about 5 C warmer Keiki646's @ a lower over clock (3.2 GHz) - But my room is about 8 F warmer than normal (73 F). @ 3.8 they are still about 5 C warmer @ my normal room temp 65F. Individual cores are more constitent (only about 2 C diff between cores both at idle and load (prime95). Have a poor HSF - Zalman 9700.

One of the charts I saw on HSF rated them on their delta to ambient (believe midpoint was 10 C @ idle. Also Back of my mind - for ever 1 C increase in ambiet there is about a 1.5 Degree increase in CPU core temp. (Someone with better memory may correct me- won't take offense)

Added - My temps are for a i5-750 NOT the system in my config (have not updated yet).

Well my ambient temps in my Apt is 66F to. That is the also has to do with two 230MM fans one intake and one outtake and two 140mm fans intaken and one 140 mm outtake. Also I added two 120mm fans on the bottom in the case next to the PSU and the other mounted on the harddrive bay..
