4670K overclocking - Themis vs Aidos?

MichaelAwkward · 13 May 2015 at 12:01

Hi, I'm looking for a new CPU cooler so that I can overclock my i5 somewhat. I used to have a H60 V2 but it was way too loud for my tastes and ended up being RMA'd after the radiator threads stripped themselves.

I'm not looking to spend much, and the reviews of the Raijintek Aidos and Themis look good. My idea was to buy either and then replace the fan with something better.

The benchmarks here don't show much difference between them, is the 120mm cooler worth the £5 extra?

Cheers

So I went with the Ereboss Core with a Scythe Kama 1600RPM fan in the end. Got a fan controller on the way so I can enjoy some peace and quiet haha.

All I've tried so far is setting CPU ratio across all cores to 44, 43 and 42 with V-core on Auto in my B85M BIOS.

I got BSOD at logon with 44, BSOD during test 6 of IntelBurnTest at 43 and it completed it at 42.

Max temps were 80, 80, 75, 71 and 80 from HWMonitor. At idle temps are 28-31.

Any tips or is this as much as I can expect?

EDIT: Also, in the process of installing I had to remove the heatspreader from one stick of my Patriot 2x4GB DDR3 kit, and in the process chipped the PCB. It seems fine, I ran memtest86 from a USB stick and no errors were reported. Is it safe to keep using it?

Nice to see that B85 boards can still clock K series i5 cpu's. Which board do you have? Depending on the options in the bios you should get more than that. Increasing vcore will be neccessary but some boards are capped at 1.2v. I easily got 4.4Ghz on my 4670k in the wifes Gigabyte B85M-D3H with exactly the same settings as my Hero. It look's like you will become temp limited quite quickly though. Running a pair of fan's in push/pull may help with that.

Memory tends just not to work if it's damaged so you could be lucky with that. If it's working ok just use it.

It's an Asrock B85M Pro4. I wanted to upgrade from my 2 memory slot ITX board so this was the cheapest way whilst retaining the ability to OC.

I've found a "Quick & Dirty" guide by Intel God so I'll give that a go and see how I get on. I just reseated the heatsink too because I was sure it wasn't on properly. It doesn't have the most intuitive mounting process!

I just set the Vcore to 1.25V, left Input at 1.9V, set multiplier to 44x and it seems stable. Completes 10 goes of IntelBurnTest.

Maximum temperatures are 92, 89, 84, 80 and 92 respectively from HWMonitor. I tried reducing Vcore to 1.24V but it BSOD after a couple of minutes in Windows. Idle is 28-31.

Is it worth bothering about with any more? I was going to faff around with a fan controller but it seems pointless when all my other fans are running fine off the motherboard (5 headers, 5 fans). There isn't actually space for push pull with this heatsink on my motherboard.

You shouldnt really be using IBT for stablity testing,x264 or realbench are better due to not having AVX instructions.

However you look fine,real world heavy usage gaming/encoding ect should be in the high 60's or low 70s.Which is fine for a 4670k

MichaelAwkward · 19 May 2015 at 15:10

Yeah I just tried some other benchmarks including RealBench and Prime95.

However I was getting BSODs with Prime95. So I've gone back down to 43x multiplier and it passes everything no problem.

Maximum temperature is 73 with RealBench and 90 with Prime95 after 10 minutes. I'm guessing if I upped to 1.3 on VCore it'd manage at 44x?

EDIT: Nope, BSOD after a few mins of Prime95 at 44x with 1.3v.

Prime also uses AVX coding so that's why the temps are higher than Realbench. Do you have LLC on that boards bios. If so try setting it fairly high. I reckon that 44x just needs a bit of tweaking as 1.3v should be enough really. You can go to 1.35v but watch the temps.

MichaelAwkward · 19 May 2015 at 19:21

It does have LLC. I'll have a play with it.

MichaelAwkward · 21 May 2015 at 16:35

Enabling that seems to have done the trick. It's stable at 4.4Ghz now, at 1.3v.

Completes Intel Burn Test, highest temp 100, and RealBench, highest temp 83. Idle at 35-39. This is with fans on silent mode in the BIOS. On standard mode they're a bit too loud for my liking, and they only knock about 5 degrees off compared to silent.

IBT uses AVX coding as well so that explains the higher temps again. Glad that worked but it look's like that's your lot now due to the temps.
