Bringing The temperature Down

[Rahulsingh190]

I have i5 4670 Haswell CPU, which had really high temps 65-75*c, but after Changing the Core Voltage from 1.025V to 0.500V, its now nearly at 50-60*c, i'm using Intel Extreme Tuning Utility, But i found One more option "Processor Current Limit", which is now set to 1000A. So, i think lowering this current limit Could bring the Temperature Down further, But I'm not sure, if it would be safe to lower this Current Limit, Considering the life of processor in long term, and If its safe, what Value (ampere), should i set it to? i can sacrifice performance to bring the temps down.

My Build :

- i5 4670
- GeForce GT 620
- Corsair Vengence 1600Mhz DDR3 RAM

thank you

Is this temperature under load? Are you using the stock cooler?

get a better cooler, leave those options alone, reducing voltage could cause instability, and it'll take as much current as it needs, but i'd suggest that 1000amps is a technical limit and will make no difference. 1000A at 1V or thereabouts is 1KW, and you don't have a 1KW processor.

I am confused as to how that is even running...

The Lower Temps From Both the Cases are the temps (i.e. 50 & 65) when Idle, And Now after changing the Core Voltage to 0.500V and Setting the Maximum CPU Usage as 50% in Windows The Idle Temp is 50*C, and when Gaming (GTA Vice City), its 60-65*c. And Previously While Gaming (or some other CPU intensive Task) it used to reach 75-90*c (90*C Sometimes). Yes its the Stock Cpu Cooler, with the Deep cool Thermal Paste.

50-65 at idle makes it likely the HSF is badly fitted with the pushpins not fully engaged, quite common, and the push pins are a pain because you need apply a lot of pressure.

at 0.5V you WILL experience instability, reset that back to auto. How much thermal paste did you use? What are your ambient temps? What's the mobo temp, i.e. the temp inside your case/box.

You try making sure the cooler is seated properly, but remember to clean and reapply the thermal paste if you remove the cooler. As you are not using the pre-applied thermal paste make sure it spreads evenly on the cooler as I found this improved my temperatures by around 10 degrees.

Agreed, I'm assuming that something is overiding that voltage or it's a delta and is actually -0.005V i.e. the smallest redcuing increment. Either way something is not as it appears.

here is the screenshot

And theres no instability

what about the cooler push pins, and how much thermal paste did you use, and what are your ambient temps. I actually don't care about the settings as it will work on stock at safe temps if everything is on auto, and the cooler is fitted well unless you are living at 40+C .

it's not actually at 0.5V it's a proposed value, It will not work at that voltage, and it's not the solution to your problem.

ambient temp is mostly 30*c, actually, one of the pin, never fits Properly (i.e doesn't makes a tick sound, when pushed), but also it isn't loose, cause i've to pull it hard to, while removing the heat sink. and the thermal paste was just enough.

 

[Rahulsingh190]

i'll try to fit the heat sink properly and see what happens, and thanks all of you.

It absolutely must make the click sound, this is the source of your problem, it will fit, they all do, they need to apply a lot of pressure to the CPU, i've seen mobo's bend with the pressure they put on. don't remove it else you'll need more paste, just make that leg fit. How much paste did you use?

Thank you very much, now the temp is 41.40*C, i never had temps this low.

excellent.
