lol xD it's 5C in your room? Playing in fridge?

Finally, just enabled PLL overvolt in bios and I've been able to boot at 46x...

room temp should be near 20-21C. 24C in bios, but core at idle are like 30-32C.

While gaming, it's less hot than my X4 635...
Not in a fridge, in canada with the window open :roll:

Mine is closed :eek:

But for AMD vs Intel temp, I was looking at the exhaust top of my case, when I'm gaming, it was hotter on the AMD CPU...

well going to bed, I'll keep running Prime95 4.6ghz 1.28v

BTW max core temp : 68C for now.

Just for a feedback, since I couldn't get for now the corsair H100, I did a small mod. Removed the actual fan of the CNPS10x Extreme, and put a Coolermaster R4 blue led 120mm.





You need to remove all the fan fitting, except the plastic that you screw in. By the way, the heatsink is very similar to an ultra 120.. maybe a bit bigger, but is it similar lol. Fan is being controlled by a Zalman Fan mate 2. max speed, is much quieter than the Stock fan at max speed.

Result: Drop the prime95 temp from 67-68 highest core, to 58-59C 4.5ghz @ 1.256v, which is a not bad result :)

Will see if I can try fittign a pull fan also, and see if I get better result. This will let me wait a bit for my H100 :cool:

P.S. Sorry it's still a bit dusty :laugh:

oh... WHAT THA HELL MAN :eek:

I should try that mod too on my CNPS 10X Extreme.

I'm getting idle temps of 20ºC and around 50ºC in prime95 with this cold weather, gotta try a good CFN fan in here and see the improvement.

btw, you need to take the cooler out to unmount the original fan, or is it easy to take the fan out?

I was able to take it out in the case, you just need a small screw driver, and you need to remove your ram

You will need to take off the 4 screw of the fan, then you will get 2 screw under the fan you need to take off. Then you will be able to remove the top fan controller. You keep the plastic fan mounting as you need it (it's clipped on the heatsink).

for the new fan, you need a small screw driver also, to be able to pass it into the fan hole.

If you were running the CNPS10x on medium or more, you will just get same performance, but with silence. On mine, I was running it at low speed for silence, but now with the CM R4 120mm, it's high flow with low noise. I did a small cleaning also, but I don't think that could make 10C better, since it wasn't that dusty.

Thanks for the valuable info m8! :toast:

I'm getting tempted to order this fan: COOLER MASTER 90 CFM Blue, it looks like one of the best out there for high CFM + silence. What do you think?

Thanks for your reply. Do you have an idea of what cooler could be much better? Noctua cooler? I want to overclock this CPU with a safe voltage, cause maybe he will run some BOINC overclocked, so I think safe voltage is 1.35v. I'll try to keep it under 70C ;)
I'm running a 2600k at 4ghz under a corsair A50, my temps stay in the high 60'ties when crunching

As promised, here is my feedback after modding the Zalman CNPS 10X Extreme!

Here is the baby naked :laugh:



After being mounted:



Prime95 and IBT were run for 15 minutes approx.
Room temp: aprox. 20ºC





The benchmarks with the R4 were run with the room temp a bit higher, but still performed great.
An look at this:

I based myself in a 1 to 10 rating wich i consider:
1 to 3 - you can't almost hear the fan.
4 to 6 - you hear the spinning a bit.
7 to 10 - irritating noise coming from the fan.




I know this is not a solid rating but... this fan is just extremely quiet! Look at it @ 1300RPM and you can barely hear it! (my case fans were actually louder)
I find this fan at 1800RPM is quieter than the Zalman one at 1600RPM, much quieter...
I set the R4 to 700RPM and it was almost inaudible, really good buy.

Thanks for giving me this idea! :toast:
