Intel Core i5 3570K Processor "Ivy Bridge" Quick Temps Review
Note: I'm doing PRACTICAL (real world) tests here. No hard mods or anything that can void the warranty of any hardware.
The "Ivy Bridge" Processor
Ivy stock cooler on the left, Sandy on the right. Difference is only the color of the Intel sticker. Everything else are the same.
The test setup:
I used two coolers for this test
Intel Stock and Noctua NH-U12P SE2
Intel Core i5 3570K Processor
Asrock Z77 Extreme 4 Motherboard
Gskill 8GB (4GBx2) RED DDR3-1600 Memory
Sapphire Radeon HD7870 2GB GHz Edition Video Card
FSP Everest 800W Modular Power Supply
Seagate 1TB Barracuda HDD
Choosing the right thermal paste is not really a big deal right now. Since most of the current branded ones perform really good. If there is a difference it is just going to be 1-2 degrees C. For this test, I used Noctua's NT-H1.
This is the workbench. All the tests are done OUTSIDE the casing. I'll be doing the "in-case" tests later.
On to the temperature scores!
Ran Prime95 64bit Small FFTs Torture test for at least 1 hour. (6hours for Overclocking stability test)
I don't really mind minimum temps, so let us focus on the MAX values.
--------------------------------------------
Using Intel Stock Cooler
with Noctua NH-U12P SE2
--------------------------------------------
OC temps, all using Noctua cooler:
*each processsor (even w/ the same model) are not the same, some can run the same clocks speeds w/ lower voltage while others may need to increase more.
4.2GHz, Vcore @ 1.24v (crashes at 1.23v)
4.2GHz, Vcore @ 1.24v
AIRCON OFF
4.5GHz, Vcore @ 1.3v (crashes at 1.29v)
4.5GHz, Vcore @ 1.3v
AIRCON OFF
Just for reference I have a screen shot of my Intel Core i7 2600K "
Sandy Bridge" w/ HyperThreading OFF.
2600K, 4.5GHz @ 1.37v, HT off, inside CM Cosmos II casing (all silent fans, one at mid speed), AIRCON OFF
Using Noctua NH-D14 w/ Deepcool UF140 fans (lesser noise). The default Noctua fans are better.
Instances like these (FULL 100% CPU LOAD) only happen when doing video / 3D rendering like jobs. Real world usage like Word Processing, Spreadsheets, Presentations, Internet, Photo / Video Editing, CAD applications etc.. only 1%-60%
random load.
Also, most games are GPU (Video card) dependent. So you rarely (or never) get max temps when playing.
4.5GHz. Ran Crysis2, Metro 2033, Batman Arkham Asylum, Skyrim etc...
AIRCON OFF. I wasn't able to try Starcraft II on this system, it might bump it higher a little bit, but for sure still under 70C.
I tried 4.6GHz also, but wasn't really able to have time to test it for stability, temps went up to 85degC (aircon off). 4.7GHz and up, needs more than 1.4v of Vcore. Again, I'm testing for real-world usage. For sure, nobody is comfortable with their processor temps going beyond 90degC 24/7 hehehe.
CONCLUSION:
Intel's new Ivy Bridge core processors are definitely hotter than its predecessor, Sandy Bridge. When using it at stock clock speeds, there is no issues at all. The old Prescott was even hotter and it was pretty good in the market.
The real issue here is the processor's temperatures when
overclocked. This thing could produce 4-8 degrees more heat over Sandy. But, let us think "REAL WORLD USAGE". It is not every day that you make it run 100% load for hours. A lot of these professionals (the real ones) who do a lot of "rendering" don't even know what "overclocking" means, in short this little heat issue is not a big problem. Aside from that, most of you people reading this, don’t even do slight of those rending jobs. Facebook and games, admit it! LOL! Kidding! Seriously, if you are afraid of much heat, just simply use a better cooler, lower your overclock (4.2GHz fairly good) or if you are so paranoid then do not overclock at all, you don’t deserve it! Hehehe.
If we talk about performance, Ivy performs better than Sandy Bridge in a small margin. So, if you are currently using a Core i5 2500K or i7 2600K or any high-end Sandy core, there is no reason for an upgrade. Unless you really want to coz you have money. But if you are going to build a new system or upgrade from Core 2, first gen i5, i7 (or any AMD processor :P), then go for Ivy Bridge.
I hope I am of help here. Just post in comments or questions, I’ll try to answer as much as possible. I am not a PRO, extreme, Elite modder or an Expert, but all I can say is I have “a bit” of experience.
*I would like add something about i7. Normally Core i7 runs hotter than i5 due to its HyperThreading feature. By disabling it, temps will dramatically go down by 3-6 degrees on LOAD. So again, if you are not one of those who does "professional renderings", HT is not really necessary. Most applications and games don't use Hyper Threading.

unta naa pud thread sa process of effective overclocking.... for sure many (im one of those) would like to have it from a fellow istoryan... (",)
