Planning on getting an i5 4690k, wondering if overclocking will be possible on with my cooler.

RustyRagdoll · Aug 22, 2017

Greetings,
so i'm planning on switching from my current i5 4440 (@3.3ghz) to an i5 4690k (also considered the i7 4790k, turns out it's not worth the price difference).
And i was wondering if my CPU Cooler could handle an overclock to 4.2ghz on it without any worrying temperatures (what i mean by this is more than 65ºC).
I'm quite an expert at GPU Overclocking but i know next to nothing on CPU Overclocking, so that's why i'm asking you guys, here at Tom's Hardware.

Specs (other than the mentioned CPU)
-The CPU Cooler in question: Raijintek Aidos Direct Contact Cooler (http://www.raijintek.com/en/products_detail.php?ProductID=2)
Has served my i5 4440 very well, has never gone over 54ºC)

-ASUS B85M-G PLUS Mobo
-16GB DDR3 RAM
-750W PSU
-Tons of case fans, around 9 total

Thanks everyone.

my 4690k is running at 4.2 ghz on a Hyper 212 evo and it stays nice and cool. at gaming load it sits around 60 degrees. lots of airflow in my case though so this may be a bit lower than a smaller mid tower

That cooler will do a decent overclock on that chip. But I don't know if it will be worth the trouble as overclocking on that board will not be easy. The only way to overclock that board is to overclock the base clock (BLCK). This will impact your RAM and PCIe slots overclock. Getting the right voltage may be an issue as well. You may also have to roll back your bios to a certain revision to support changing the BLCK. For me, the performance gain is really not worth the trouble.

not on that mobo.

I dont have temp issues with my and it is over clock with almost the same cooler - Freezer i30. Just to know the room temperature also should be consider because this is air cooling and you cant never drop below room temp.

After a bit of research, it seems that with this motherboard i'm able to overclock the CPU thanks to an update that dropped in 2013. (http://forums.hardwarezone.com.sg/hardware-clinic-2/overclock-your-asus-b85-h87-bios-update-4296226.html)

I know that the B85 chip isn't made for overclocking and has very little tolerance to it, but this update will do it some "justice".
Let's say... a target of 4.0Ghz would be easy?
If it's easily achievable, i'm happy.

Thanks everyone.

If you can change the multiplier, then yes 4.0 Ghz should be easy enough. Your CPU already turbos at 3.9 Ghz so it is pretty much already there.

Thanks for the answer.
But concerning what i asked first, if my cooler would get some solid temps after the overclock, what's your take on it?
And also, what maximum frequency do you estimate i could get with my B85 chip?

Math Geek · Aug 22, 2017

yah i just let my mobo software do a "safe' oc. 1 button click and it did it for me. 4.2 ghz easy

there are higher settings but i'm ok with what it did

RustyRagdoll :

The max frequency has too much to do with the CPU. Since your chip turbos to 3.9, I would have the expectation that the CPU would OC to at least 4.0.

But your motherboard VRMs were not designed for overclocking despite the bios update. I am not saying that you wont get to 4.2, but a quality motherboard also has a big impact on stable clocks.

Your cooler will be fine to overclock the chip. Don't worry about that.

Alright, thanks for the answer.
But i should atleast get a 4.0Ghz overclock without instabilities right?
I'm planning on leaving it at 4.0Ghz (maybe 4.1Ghz if possible) and the base clock at 3.0Ghz if possible.

You should get 4ghz. But no one can say for certain because you are clocking the chip past it tolerance. But since the boost of the chip is 3.9 adding an extra 100mhz is only about a 3% increase from boost, so your not asking for much. I would be very surprised if you could not hit 4ghz.

If you set the chip to run at 4ghz, the base clock will be 4ghz. You cannot change the base clock and the boost clock. You can only change the base.

Personally I would save a few bucks and choose the 4690 if it's available and less expensive. My 4690K overclocks easily to 4.4GHz, with a 212 Evo cooling it, but then overclocking becomes a bit trickier after that. However that is on a Z97 board designed with OC'ing in mind with the passive coolers, power and whatever else goes into an OC friendly board. Look around your CPU. See any coolers? That's a message saying please don't OC me. I wouldn't spend more on a possible 200MHz.

Yes, that cooler will be just fine with a 4690K OC'd. Consider https://www.techpowerup.com/reviews/Raijintek/Aidos/6.html What is surprising, however, is that the much smaller Aidos beats the Cooler Master Hyper 212 EVO and NZXT Respire T40 by 1°C and 4-5°C respectively, at both stock and overclock,.

Actually my mobo has a medium sized ASUS passive cooler on it so i'm not sure. (https://www.asus.com/media/global/products/4ylw5BywjMzIPvCS/8F1nUEJVS2fVDRDl_setting_fff_1_90_end_500.png)
But my board actually has some "reinforced" components written on the box, and in the spec sheet. Some are:
-Capacitors (2.5x stronger than traditional)
-I/O (3x stronger than traditional)
-Also has "tons" (well, 3) overcurrent protections...

RustyRagdoll :

I did see your motherboard when I posted my answer. That is a passive cooler for the southbridge. I suggested looking around your CPU.

. That for the VRMs. The more power that goes through them, the more cooling is needed.

You see there are two major differences between your board and mine. No extra cooling on yours is one. A 4pin CPU(sometimes referred to an EPS 12V socket) power connector on your board. An 8 pin connector on my board. Those are two indications that OC'ing isn't recommended with your board. My board has access to more power and better cooling.
