What are average idle cpu temps?

My t5750 idles at around 43-45C, and around 55-75 under load or gaming, is that normal?

 

That C2D shouldn't hit 75C; mid-60s is more normal. Have you cleaned out the laptop for dust and debris?

 

I get about 38-41 idle with an x9000


Have you tried undervolting your CPU to drop your temps?

But its pretty normal temps for the t5750

 

not normal at all. Try to lift it too if it's not already done. Mine is undervolted too is at 35 while on the internet. I reached 77 one time, but it was not undervolted, not lifted and I tryed to get it get as hot as possible to know it's maximum.(stressed cpu and gpu at the same time I think)

 

I have an XPS m1530 and my cpu is getting about 81c while gaming. Is that too hot?

 

81C is a pretty hot.

Have you tried undervolting and cleaning your systems heatsinks.

I would personally start to worry if my system temps ever rose above 55C, but you are usually safe up to about 65-70C, your system should not be running at 81C.

You should try undervolting, and than try shutting off background processes which are eating up you cpu cycles.

Hi.

what software are you using to read your temperatures?

 

core temp, hwmonitor, cpu rightmark are all good programs to read cpu temperatures.
rivatuner works great for monitoring graphics temperatures
hdtune works good for reading harddrive temperatures.

Do not use speedfan for temperatures, it is usually always wrong.

intel said 85 is the max temp of this processor, so yea it's too hot.

Core temp gave me the closer temp to the real one.

 

I use speedfan to read my temps
Also i have no idea how to undervolt.

I get around 70-75 on both cores while playing cod4 for around 1-2 hours.
around 45 while on the internet and 50-52 while watching movies/videos.

 

also, its a brand new laptop, just under 2 weeks old, there isnt any dust or debris near the fan.

 

flipfire made a very easy to follow guide for undervolting:

Just download cpu rightmark, and follow the guide, andd test for stability ang you should be fine.

Plus search through the guide for a T5750, and you should find what voltages are stable with the processor, so you dont haev to check stability for each multiplier.

Also undervolting does not reduce cpu performance, so you really have nothing to loose.

Just keep in mind the risks - your system could be come unstable and BSOD, and in my case, I lost the usability of my Vista installation (although I'm pretty sure I'm the exception to the rule).

Make sure you have a backup before performing any tweaks, as a rule of thumb.

 

could undervolting void the warranty?

 

No
..............

 

no undervolting is completely safe. The worst that can happen is a blue screen. Than when it reboots, rightmark puts the voltages back to stock.
So just keep going at it until you maximize your cooling and efficiency of your processor.

sounds like while you were testing undervolting you set it so rmclock would apply the voltages on startup... you should only do that after youve found stable voltages.

basically you should have it set so that it will not change your voltages on startup while youre testing because if youre doing it right you WILL get a BSOD at some point, and if you have it set on startup chances are youll BSOD every time you load the os . then when youre sure its stable you set it to apply voltages on startup.

unless thats not the issue... either way reinstalls are nice

 

If this did happen just boot into safe mode and disable run at startup!

 

Vicarious, that wasn't the case. I set up an undervolt, went into TF2, which crashed my system hard. Flickering green and all that.
I did a hard shut down, and then Vista failed to boot.
My screwup was failing to ORTHOS test sufficiently.

 

how long should i test in order to consider it stable?
so far ive come down to 1.0750V on 12.0x multi with 1 hr 45 min of ortho running and still going.

 

did you manage to fix it?

 

Well, yeah - by doing a fresh install of Vista Ultimate.
I might begin to undervolt again, but not until I have a new Complete PC Backup.

 

Mine is at 1.0375 for 12x and every other a minimum. But maybe you can lower it further, others managed to lower it to minimum too(12x)

 

I would say that the worst thing that could happen is if it blue screens AND corrupt files so you may not be able to boot up the OS and have to do a fresh install in order to fix it (when you lose the abillity to recover in any other way). Otherwise it's completely safe, i agree!

 

how much is minimum??

 

The minimum allowable is .950 V.

 

rightmark only has a limite amount of voltages which the processor can be set to. The lowest being 0.950V and the highest is 1.450V.

K-TRON

 

40 average, 69 while gaming, i have it undervolted at 1.0750 from 6.0x tru 12.0x

 

In the process of undervolting right now.
From 86 degrees max on stock voltage 1.225V to 62 degrees at 1.05V.
Gonna keep plugging and see how low I can go, then give it an hour-long ORTHOS grind.
After I went below 1.1V, my system also stopped going into thermal throttling mode. This is VERY encouraging.

 

Mine idles between 30 and 36 degrees, but it's undervolted @ 0.95V, except for highest multiplier which is at 1.0625V.

I think mine's lower because it is a Penryn 45nm.

 

Probably - although mine idles at around 35-40 even before UVing.
And speaking of which, I've decided to hold at 1.025V for 11x. It's 0.2V below stock, drops my temps by QUITE a sizable margin (not sure how much though, as my room temp's dropped too), and hasn't caused a thermal trip once through 35 minutes of ORTHOS.
All the other multipliers seem stable too.
I'll give it some 3DMarking and a little bit of TF2, and get back to you.

Heh - it'd be great if I ultimately UV my CPU and OC my GPU (or at least its shaders).

EDIT: Ran a few 3DMark06 runs w/o any CPU problems...it's just that Deep Freeze is running about 3 fps slower for some reason I don't quite know. Going to TF2 now.

EDIT 2: TF2 ran just fine. I think I'm gonna let this thing run ORTHOS for most of tomorrow before I pass official judgment on its stability.

 

Unvervolting won't affect idle temps.

I idle at 24-26c on my DV9700T and with undervolting I have load temps of 43-45c now. I used to reach 60c before I undervolted.

My 8600GS card idles at 46-48c and load so far is 53c

The main benefit for me is the extra battery life. I have 2 hard drives in my notebook so I lose about 20 minutes of battery life with the extra HD, but gain 30 with undervolting.

 

Of course it will, less voltage = less heat! even at idle!

 

Not in my experience, it only affects load temps. Umm, Mostly because the lowest multiplier on the penryn is already volted to the lowest amount at .950
