Replacing stock cooling, intel i5

[TIZ012]

Hey guys this is my first post, I started annoying Tom a bit too much with my youtube posting questions lol. (Sorry Tom) All these temp results are for stock speed of CPU @2.8GHz

Right I got a few questions, but I will first will inform you about my system with stock cooling, temps before and cooling, temps after.

With stock was getting about 40 degrees C idle temperature which easily reached 75 degrees C when playing games for +2 hours (Heavy games like Bad Company 2, GTA:LC etc.)

Messed up first installation of my Arctic Freezer pro rev.2

Installed for second time correctly I think. I used Thermal Compound Arctic MX-3, which does state no curing time (used the vertical line method which is correct for i5's).

I'm not sure what this means exactly, can I start my PC up straight after applying and go crazy start playing games and benching or not, do I have to wait for it to fill in all the cracks?

I installed the cooler and when I opened up CoreTemp it was showing as low as 18 degrees C on 3/4 of my cores on the 4th core it was 24 C and it never went as low as the other 3 cores, my 2nd question is was that normal behavier?

I kept my PC on and as I started browsing the internet and joined OC3D quickly (while listning to music on youtube) the temps shot up to as high as 30C while on idle. At this higher idle temperatures the 4th core balanced out with the other 3 cores and the temps were very similar all within 29C-33C...so average was 31C. My question is, is this normal? Why did it suddenly decide that 30C is my idle, and why on higher temps all cores are similar in temps but on as low as 18C one core is 7C higher than the rest?

Is MX-3 not set in, did I apply thermal compound correctly? Did I install the Arctic Freezer Pro rev.2 correctly?

hi,

intel i5 has speed step feature wich runs the i5 at different frequency's depending what it's doing, delivering performance and protection. when th pc is idling the i5 works on lower frequency making little heat. you used wmp, ie, oc3d and the i5 makes extra heat because it's processing extra stuff like music decoding, streaming, internet stuff. the little heat is held for a long time, slowly dispersing. those temps are ok as each core is loaded differently.

if you can describe how or give me a link to the vertical line i5 thermal compound method do please.

It'd be useful for other users to know your loaded gaming temps

Yeah speed step is definetly the most probable thing. But with stock it was weird when doing small things like browsing and youtube temps stayed between 40C-42C so I naturaly assumed the same would happen with this cooler they would stay around 19C-24C, but unfortunatly not. Still way lower temps than before. I will run temp tests and upload them soon to this thread and also the info on the vertical line method so you and others can see whats happening in more detail. Anway thanks for the quick reply dude.

That was a quick half an hour test in Prime95, with an overclock to @3.590GHz (Not sure if I overclocked correctly, if you think my multiplier or BLCK is wrong plz advise thanks). As you can see the temperatures were very high. One core peaked at 79C but went back down to 76C during the last test before I stopped it. I think this is way too high to keep as an overclock, correct?

Thanks Tiz

(Edit: Does anyone think that running Prime95 much longer would have been better? To see If it gets even hotter and make sure its stable at those high temperatures?)

I think they are normal temps as I've had similar temps with i5 750 @ 3.7Ghz with a similar sized cooler, the Coolermaster Hyper TX 3. I've not tested my i5 with prime 95 so I'm not certain. BCLK and Ratio is OK. High performance motherboards support high BCLK frequencys. I think your safe for your board

I don't know if it's a good overclocker.

Maby try ASUS Turbo V for an easy performance auto overclock. It put the i5 750 to 3.7Ghz stable on a high performance board with BCLK 195 RATIO 19

Thanks dude, I did a bit of research and I released that overclocking using software or automatic settings from my mobo isn't the best way to go. I think yeah my mobo supports good overclocks seen it being used to get my i5 760 stable @4GHz. Problem is I think I need more powerful PSU for entire system to be stable, also thinking of upgrading my GPU to a GTX560 Ti (requires more power) so overclocking will not be possile for me. I want to buy a Corsair TX850 PSU which should coupe well with CPU/GPU/RAM overclocking and should support additional SLI/Crossfire config.

But thanks for the reply dude

high performance boards will run high BCLK values and 4Ghz 24/7 style forever. That ASUS P7P55D-E board you have might not cope due to lower qualtiy and less capable components. I don't recommend using 4Ghz. ASUS's Turbo V auto overclocker is good because it sets the values into the system BIOS permenantly till you reset or configure the BIOS. That gives you a general idea on what your processor need to run and you can tweek the auto setting to try and run on a lower voltage or different frequency, higher frequency maby with more voltage. ASUS is very good for auto overclocking.m I've read and seen good stuff for Torbo V and it's server me well always. It's perfect for a new begining to overclocking.

The basic ASUS Turbo software is for my old h55 board and that doesn't set the overclocks to permanent values and its auto settings are small overclocks. People commented on that not being effecient as it had to be used every re-start of the PC to overclock so it's easier to put values into the BIOS, like TurboV.

If your computer crashes by un-stable overclock by way-out values you might have a big job to get it to boot to BIOS for configuring.
