I5 760 Temps

[MitchC]

Hi.

As of recently I've been intrigued by my CPU's temperatures. First I'll go through the specs:

I5 760 @ 3.2GHz
+ Artic Freezer Pro 7 Rev 2
+ Recently applied thermal paste

I did do quite a bit reading before I decided to put this up but from what I could gather, my processor is some what warmer then the majority of everyone else's.

Idle (warm day) roughly: 45, 48, 42, 46
Gaming load (warm day): 64 tops on any core

I'm using both real temp & core temp to get these readings.

Even when with the stock cooler and running at stock speeds (2.8 GHz) It was hanging around the idle mark of 50+ on each core.

Now the one thing I did notice compared to a few other people with this processor is that my temperatures don't raise no where near as much as they do if they use something such as prime95. (Once again max temps with prime95 for 5-10 mins is around 65)

So I guess my question is, will these temperatures effect the life time / stability and or health of the CPU? (I've been using this chip for around... 5 months now)


Thanks in advance,

Mitch.

As long as the top temp is below 70c you're fine. You're CPU shouldn't have a shortened life at temps like that. However, cooler temps usually means longer life, so more case fans maybe?

Stock coolers are always relatively hot compared to bigger 3rd party coolers and that's supposed to be the normal setup and cooling, it's the manufacturers own design cooler.

Temps, 20 degrees rise is normal under heavy load.

Your idle temps being about 45 average will be down to airflow unless you have some crazy volts on the processor.

If you're interested, this is my i5 750 arrangement:

160 x auto
+ Turbo
+ Speedstep
+ Load Line Calibration

CPU volts @ 1.15625V
CPU PLL @ 1.80200V
IMC volts @ 1.12625V
DRAM @ 1.60325V

I have speedstep on and the ratio is on automatic so on idle I'm on 1.446GHz on load it goes up to 3.374GHz

Current ambient is 23 degrees, CPU is at 30 average.

Temps with Prime95 are up to 50 degrees
Temps with IBT/LinX are up to 60 degrees

The main thing about lower temps is how fast your rig can dump heat (ideally without making much noise).

I got a bit keen when arranging the cooling (honestly it's very quiet):

But you don't need all that, as Mitch said you're well within proper temps, if you particularly want to lower them then there's various things from seeing if you can lower the volts on your processor, maybe enabling energy saving options, to making your cooling more effective.

Why do people think 70c is the max ? I ran IBT 50 times on my 750 at 4ghz 1.4 volts and it hovered around 70-83c and hit 85c on one core and was fine.You shouldn't worry really yes ideally you'd want to get another cooler so gaming load is 50-60c but 70c isn't going to kill it any time soon.Which thermal paste did you use ? and which spread method ?

You have so many fans around your radiator....

If you are concerned by the temperatures add a second fan to the back of the freezer with some cable ties or similar. Turns them into a stellar performer for the price

Yes and no.

It looks like 5 fans. Reality is there are 2 fans. The apparently double case fans are also only single fans.

The other 3 "fans" were fans. Now they are shrouds for the real fans. Shrouds are fans with the fan part cut out. Or if you want to be flash you can buy basically the same thing but milled from a block of plastic.

In theory the shrouds help with cooling with a radiator as there's less of a dead space caused by the fan motor being stuck against the radiator fins also less turbulence with air entering and leaving the fan.

Here's a youtube video about it: http://www.youtube.com/watch?v=MYbG-uv4Op4

Noise can increase due to increased airflow but the fans are set to 1200rpm which is audible (there are 4 x 120mm fans after all in total) but it's relatively quiet and definitely not the turbine it looks like it would sound like.

It can be much louder (and only slightly cooler) if everything is set to full speed and fan filters are removed. Special occasions only
