Too hot? i5-760 and 2 GTX 460 in SLI

Last response: in CPUs
December 4, 2010 7:25:07 PM

while idle, my core temperatures are between 29-33 for all four readings
using Realtemp

In Prime95 stress test, the cores went up to 75-79 within 2 min so i stopped the test.
I haven't stressed the GPUs yet.
I am mainly concerned about the CPU temp. When installing, I installed the CPU fan/ removed it due to cable tangling and reseated it (properly as far as I can tell) so that has me worried about the the thermal paste.
The system components are

CPU: I5-760 with stock fan/paste
Mobo: Asus Maximus III formula
Ram: Corsair 4gb DDR3 1600
GPU: 2X GTX460
Sound: sound blaster X-fi
HDD: Seagate 1tb 7200 (runs at 28 for temp)
Case haf922

Is the temp in the normal range?

Edit: ambient temp is around 70 degrees F

to high. You want to stay under 70c especially at stock. I'd remove it, remove the thermal paste and reapply.

While I concur with Vindictive as even for the SHI%$ stock HSF, your temps are much higher than they should be unless you live in the "Down Under - it summer there, or the tropics.

Myself I DO NOT even install the intell stock cooler (Just look up SupremeLaws comements). They are close to the BOTTOM of the list for effectiveness - and thats if you get them insalled GOOD. I prefer HSF with a Backing plate ( I use the Zalman 9500 on E6400 @3.2 and the 9700 on my I5-750 NOTE at 3.8 GHZ my max temp was 62C.
This is not a recomendation for the Zalman, better ones are out there and at a lower price.

As hinted by RetiredChief, get an aftermarket CPU cooler.. Even a cheap one such as the CoolerMaster Hyper 212 plus will yield better results compared to the stock Intel cooler..

A nice dense rock will yield better results than the thing Intel gives us xD

If you dont plan on oCing, undervolt the crap out of it, ur heat will drop :p

Thanks everyone, I ended up ordering hyper212 plus and artic thermal compound. i Also got another 200mm fan to help with the airflow...

What is the lowest volt i5 can handle? a quick rundown on how to manage voltage will be greatly appreciated as I have no experience with oc-ing...

there is no set stadart, start going down in small increments untill your system becomes unstables. For my 955 I would run prime95 for around 20 min with each change, settled for 1.2v with 200mhz OC :p 

Best solution

For stable operation, I would say don't go below 1 V (from looking at a couple of threads about 1.05)

That said. Power does not always go down when you undervolt a CPU.
Two things are fixed P=ExI and I = E/R. with a Resistor it is a given, if you decrease E then I goes down and Power goes down. Power goes in the direction of Cause - in this case cause is decrese in E. This aften is not the same with a active component such as an IC. The problem here is that quite often when you decrease the input voltage to a circuit, Current does not always go down, infact oten increses and may infact increse power. To save a couple of Watts, not worth it.

Bottom Line - The change in HSF should cure your problem, don't sweat the undervolting.
