So I got this chip for free, I was going to buy a 6600K chip and over lock it but since I got the 6500 out of an HP desktop that was destined for the computer parts disposal place I built a gaming machine with it. I made sure I bought a Z170 motherboard so I could do the overclock.

I found a guide with the bios and instructions for over locking this chip and they reckon I should be able to get about 4.4ghz out of it. What I want to know is what cooler should I be looking at? About 5 years ago I got an I7-2600k up to about 4.5GHZ stable using a corsair H70 water kit. Any reccomendations on what I should get to cool this chip before I overclock it?

Apparently the small architecture (small nm) makes this very hard to achieve stable overclock due to poor heat dissipation.

It baffles me that a chip smaller than my thumb needs coolers larger than a room.

That's bad design not good design!

I like noctua air coolers personally, but I've never bothered with overclocking. If it helps: I went for a big top down, I forget the model (two 3-pin w/ultra low noise adapters), and under load my I5-6600 at stock tops out at 43°C and sustain near full turbo, even with a fan heater sitting right under my tower.

I know two people with the same CPU and they recommend the Noctua-D14. It should be pretty widely available in NZ and is a well-reviewed, established air cooler. Just a few quick words of advice and questions in an attempt to further help (as someone who has OCed other chips before):

1. Don't take other people's OCing results as gospel. They managed X speed in their case and their ambient conditions etc. Take the generally agreed-to max and start off at around 75 to 80% of that speed at the most and slowly build up and evaluate temperature and stability etc.

2. Can I ask what games do you play, darylblake? And what video card do you use? What resolution do you game at? If you are gaming at 1080p, your FPS is more likely to be CPU limited, hence pushing the overclock (but still never at risk of excessive temperature and noise) would be more worth it. If you are gaming at 1440p (2K), you would be well advised to get at least a GTX 1070 or a second hand 980 Ti.

3. I also recommend checking out Eurogamer's review of this CPU as they detail a lot of benchmarks on what overclocking gets you. It might help you make a few decisions as to how far to push things.

Good luck.

Correct me if I'm wrong but I thought you could only properly overclock the 'K' chips and that non-K CPUs have locked multipliers?

I do remember seeing things about non-K overclocking being implemented by some motherboard vendors but I thought Intel stopped them.

Yeh I'm gaming at 1080p. Mainly overwatch and Battlefield. I love RTS games too.

The screen tops out at 61Hz so would need to replace the monitor. I'm using a gigabyte windforce GTX780.

I'm not even gonna bother getting a new card until I got a better screen which can do better refreshes.

Yeh the K versions of the chip mean you can unlock the multiplier which means yeh they are made to easily over clock. But these non k chips can be overclocked using the bclk. Their multiplier is still locked, the K models are better for overclocking. I am thinking about getting a noctua actually after doing some reading. They are quite expensive though. I hope the D15H is quiet.

Ah okay. I thought for a minute I had missed some big feature of Skylake :P

Anyway. As for the cooler, Noctua is a great choice I've used a NH-D14 before and it was the quietest cooler I have ever heard, so I assume a NH-D15 would be even better. The thing you have to keep in mind that these coolers are massive and won't fit in many cases with the main problem being the height of the cooler (width of the case).

Yeh I just read and watched this off eurogamer, going to make sure my motherboard is able to do this. (that they haven't locked the features) before I o/c the ram & base clock and buy a cooler.

http://www.eurogamer.net/articles/digitalfoundry-2016-intel-skylake-core-i5-6500-review

I think I can fit it in my case... its quite wide. I might need to move some fans around. Its an S340 NZXT.

If you have the right mobo with the right firmware you can :)

Intel left it open ...but then forced the mobo makers to update their firmwares to disallow ...

so if you mobo can do it ... don't update the bios!

http://www.computerlounge.co.nz/components/componentview.asp?partid=13524 =$169.95 which is 30 bucks cheaper the the D15 and I'd still say it was overkill unless your case is crappy

But personally if you have the room I'd go with this http://pricespy.co.nz/product.php?e=3244316 = $132.39 you also wont have a Kilo of weight hanging off you mobo

+1 for Noctua.

I wouldn't buy any other cooler.

Yeh I can't fit a D15 in my case. A D14 is the only one I can fit. But I think it will keep it cool enough to clock it to 4GHZ+. I was a bit worried about it hanging off the mono and all that weight. Does this heatsink for on socket 1151?

CM Hyper 212 is about all you'll need. Cheap and has an awesome reputation online (just check out /r/pcmasterrace).

Friend has it paired with his 6600K sitting at 4.6ghz quite happily.

Yeh well the good news is I got my i5-6500 overclocking going doing a BCLK overclock. (obviously because the multiplier is locked).

Got the right BIOS, and saved the right settings in the profiles.

I will see how I go with the cooler. Depending on how much i decide to throw at it. That 212 EVO is a pretty good cooler for the cost of it. I dont think I will bother with a small water combo cooler. Probably either that or the Noctua D14, the D15 wont fit in the case.

Would be interested to see how far this chip will go. I am reading some people are getting 4.2 Ghz some getting closer to 4.6, I guess its the luck of the draw.
