this is my build:

The cpu has been unlocked to 4 cores... looking at the temperature for the CPU the cores average at around 50 degrees sometimes below , sometimes above.... is that normal? any other way that i can check if its normal or not?

cheers

From my reading on the net I would say 50 degrees is quite hot. The max operating temp of your cpu is 75degrees. Are you using the stock cooler? Why not try replacing the heatsink with a better one? Freezer 7 pro v2 should do it. You will also have to remove the thermal paste and reapply some new stuff if you decide to change. Although I think the freezer 7 has thermal paste preapplied.

I'm no expert, but it's something i'm looking into as I'm building my own PC.

I'm using CPUID hardware monitor...the case came with a fan at the top, but a friend told me to invert it , could that be a reason? And no it hasn't caused any problems, only that i heard the longetivity of the parts become shorter with increased heat obv, so thts why im a bit worried

I don't know that case, but you want front fans blowing in, and rear/top … I don't know that case, but you want front fans blowing in, and rear/top fans extracting (sucking out).



I've always thought they were sucking in air and then blowing out

for OP info mine is running at 45C idle, though each individual core is reading at 40C so don't know which to trust, it's four core also.

ok im gona try and invert the top fan, because I didnt dable with teh front one, so I think its sucking air anyways..thx for the advice

If its a 4-pin (PWM) fan, there will likely be a setting in bios (setup) which tells the computer at what temperature to start throttling up the fan speed; this is often set to 50 or thereabouts as its was a perfectly safe long-term temperature for the CPU (prior to the last few gens of CPU), so its quite normal to have a low fan speed upto this temp and then start upping the fan speed to cool the CPU beyond that. Personally, I think 50 is a little high for idle temps, depending on what the cooling in the rest of the case is like, but its certainly nothing out of the ordinary; older CPUs like the P4 and Athlon were designed to work up 90 degrees and beyond, although a lot of the more recent AMD CPUs have lowered this value substantially...

Here's a pic of the whole thing, IM not sure about Fans speed etc, is that normal speeed? And as you see the temperature is mid 50's , thts without me playing on a game right now ..

thanks

Looks like it is PWM controlled, at only at a 41% duty cycle, so if you are concerned you could change the settings in bios and make the fan spin faster earlier. But changing the fan to an exhaust rather than an intake will probably make quite a difference to the circulation of air in the case, it sounds like all the fans are intakes which will just cause turbulence and force the hot air to sit around the CPU (remember hot air rises, hence why its generally a good idea to have exhaust at the top!)

oh ok , thanks very much for ur help, v useful!

ok it has dropped down a bit, but i had to move the fan slightly further away from the CPU... should it be directly above it?

Which fan are we talking about? The one on the CPUs heatsink or the one on the top of the case?

Original Poster Banned

the one on the top of the case... I moved it now so its on top of the heatsink.. thts the best position right? And its blowing out now too.. But still the temperature has dropped slightly still around high 40's low 50's at idle...

Well confused now, is there not already a fan on top of the heatsink? The case fan should be, as dcx says, fixed to the inside of the top of the case, blowing out. Maybe a picture would help!

Original Poster Banned

sorry i'll be clearer, its ontop of the case still obv, but positioned so that the heatsink + CPU is right underneath it

Original Poster Banned

Let me know if its still not clear, i'll take a pic or 2

Picture would help but that sounds a good position. Have you had a look in the bios (setup) settings for the fan-speed control bits? There is usually a setting that lets you control at what temp. the CPU fan speeds up, and how fast it speeds up... [Might be worth checking the motherboard manual if you aren't sure what you are doing...]

starve a cold, feed a temperature

See what you mean, makes sense now. Looks like your GPU might be passively cooled (ie no fan) - if so, temps in the case will certainly be a few degrees higher than they would otherwise be, so I wouldn't say your CPU temps are much of a surprise. Also the CPU cooler is on the small side; you could either get a beefier CPU heatsink/fan, or boost the fanspeed in bios if you are worried, but I think its probably okay as is.

GPU does have a fan on it tho.. and the temperature is pretty low on it, and so are the other componenets.... I think it might be the heatsink, the fan isn't doing that big a difference, i will look into other heatsinks, unless anyone has other suggestions? thx

Yeah, could tell for sure from the pic. Have you checked the bios yet though - your screenshot clearly shows PWM is active... If the fan is set to spin at a low rate up to a certain temp' changing the heatsink\fan won't make much difference!

Original Poster Banned

which fan would I increase then, if i did try it through the BIOS? i'm trying to find out through the manual, but not as easy as i thought :s

TBH I wouldn't worry a huge amount. It's likely your CPU will run hotter than normal as it was probably binned a x3 as it didn't hit TDP. Putting a fan on the back plate will probably help as well considering your GPU has internal exhausts.

perhaps this image will help

50 seems very high. I have a quad core amd and it runs at 27-33 idle and 40-44 when being worked hard. I did however replace the standard thermal paste with arctic silver 5 but other than that everything else is as standard. No mods or overclocking either. Get the temp down as you should see it last you a while longer.....

Going to have to pick up on that point - I've owned and used lots of computers, including lots of server hardware, and have never had or known a CPU failure. A couple of times motherboard failure from leaky caps, which could possibly be accelerated by high temps', but never a premature CPU failure; 50 degrees is really not all that hot for a CPU.

The image above is v. similar to what my pc is doing... the only thing that's missing is the Fan at the backboard as you said, however I can't see tht being the main factor for this temperature.. I saw a forum sumwhere that mentioned something about because the 4th core unlocked, the temperature monitoring programs could be wrong, and It doesnt work in such cases when looking at core temperatures seperatly... anyone know anything about that??

^I'll give it a try mr.Badass, but i dnt quite understand how it wud b improve it, surely the smart fan control helps?..

Original Poster Banned

...And nope, still around 50, goes a bit down, a bit above....when im in teh bios , it says CPU is ~30/40, but thats not the cores temperature right? well , i guess I'm gona hav to either get more fans or a bigger/better heatsink here, no other options
