Corsair outperforming Swiftech - did I screw up?

Hey all,

My buddy and I built a system at the same time.

He went with an i7 5820k and Corsair H105, pull/exhaust config.
I went with a 5930k and Swiftech H-240x, pull/exhaust config.

He's running 4.7ghz @ 30c
I'm running 4.4ghz @ 33c

The hell? Did I screw something up? Am I naturally running hotter because of the chipset? Should I be exploring adding an additional fan for a partial push/pull (the Swiftech only supports 3 fans).

Thanks
 
Solution
Did you crash, or did occt shut down the test.
Normally, the shutdown temp is 85c. or so.

It is normal for cores to have different temperatures.

If the cpu crashed, ie blue screen, then your oc parameters did not work.

Haven't done any stress testing yet (not sure what to use TBH).

I'm just debating whether or not I should keep or return the swift tech. The open loop isn't something I'm overly interested in; however it seemed across the board everyone was calling it the superior choice over Corsair and NZXT.

I just don't get how he's running more OC'd and cooler. I tried to take mine to 4.7 and the system shut down ... uhm? Honestly, I don't yet know what I'm doing. I'm relying on the Asus auto tuning crap and then just taking the clock speed higher. I'm assuming this is wrong. He did the same, ran the auto-tuning and it took him to 4.7; whereas mine went to 4.5. Odd no?

I have a single 200mm intake, a 120mm exhaust and dual 140mm exhausts on the rad. I can add another 140mm intake and swap the 200mm intake for dual 140's. Is it worth it to make any of those adjustments?

Dont auto tune at high clocks, thats your first mistake.

Autotune will take a system as far as it can and the results will not be the same across the board. Some chips need a little more juice than others to reach a certain clock speed. Some chips will do 4.7 at 1.25v and others will need 1.30 or more. Autotune cannot sense whether or not a chip will need more or less. All it does it set the voltage where it thinks it should be.

Its not as bad as it sounds though. Asus has done tons of overclocking and used statistical analysis to program their boards with voltages that work at each clock speed. This does not promise a high clock speed. Anything above 4.5 is luck. 4.7 can be had on most chips but some will require a good bit more voltage.
 
Are those idle temperatures?
What are the stress test temperatures using occt?

Do you both have the same case? Cooling will largely be determined by how much clean air you can take in.

FWIW, I think your buddy got a golden chip if he can do 4.7. Only about 11% can do that.
I have no stats for the 5930k.

@firefoxx - understood; however both of us are complete newbs and trying to read up on it online, isn't a quick and easy task. Just odd that I went to 4.4 and he went to 4.7 and my chip is slightly better.

@geofelt - Yah, idle temps. No, different cases.
What's a good way to stress the CPU? I've only been focusing on GPU via 3DMark so far.

I only have a single 200mm intake, I can convert that to dual 140's and/or add an additional 140.
 
Idle temps tell if your cooler is mounted properly. 10-15c over ambient should be typical.
You are good there.

I like the single 200mm fan for intake. It can push lots of air at lower rpm and be quieter.

To stress test, I like OCCT. Unlike prime95, occt uses more normal everyday instructions. It will stop the test at 85c. 100c. is the point where the cpu will slow down or turn off to protect itself from heat damage. Do not worry much about that.

During testing the thing to monitor is vcore. You do not want it to go past 1.35v for safe 24/7 operation.
 


There is more to auto-overclock than just the chip. The board, PSU, RAM you pick make a difference and the chip lottery of course.

TBH most of the AiO closed loop coolers are similar. Most may differentiate a few degrees, nothing insane like comparing a stock cooler to a Noctua, and maybe in the sound output of the fans.

Now what's making me nervous is after just some basic work stuff + gpu bench-marking, my CPU has been idling in the mid 40's. I turned the fans all the way up for a few minutes and couldn't get under 40.

I just have a weird feeling about keeping this swift tech vs. moving to the NZXT. The Swift Tech potential maintenance in 3 years is a bit bothersome, but I'd assume in 3 years I'll probably move to a new cooler, maybe.

I'm thinking I may need more cool air? I have 1x 200mm intake, 1x 120mm exhaust, 2x 140mm exhaust. Perhaps I'm simply not bringing enough cool air in? I have a Phanteks Enthoo Luxe, which has a front facing cover that doesn't allow for a ton of air into that 200mm intake. I have the ability to mount a 140mm along the bottom.

I just snagged the new Noctua black 3000rpm fan. I'll mount it on the bottom; however the problem is ... it will mount directly behind the 200mm intake, meaning some of that front intake's air, will be blown up from the bottom fan - think that will hurt?

If it helps, here's my overall setup (just built yesterday): http://pcpartpicker.com/p/K6CZ6h
 
To test if you have a case cooling issue, remove all of the covers.
If that makes a big difference, you need to address case cooling.

For cooling, the basic principle is to bring in most or all of your cooling air from one source which is filtered.
That keeps your case cool.

How much intake do you need?
Consider the two hot parts you need to cool.
1. a cpu which needs a 120mm fan for cooling.
2, A graphics card. A GTX980ti is really not a hot card, and the hybrid needs only a 120mm fan for it's intake.
Two 120mm case intake fans should do the job. Mount it to take cooling air from inside the case and exhaust to the outside.
If you use two 140mm intakes, so much the better.

If you use more fans, they will draw in unfiltered air from all openings, defeating the cleaning action of filtered intake.

Lastly, do not worry too much about heat.
The GTX980ti will want to target 80c regardless.
If your cpu is under 80c. under load you are ok there too.
A 200mm fan has about the same intake area as 2 140mm fans so you really should be good.

Have not yet had an opportunity to do the stress test, planning to do so this weekend.

Still at unease being that I'm running hotter at a lower OC than my buddy, so I snagged an extra 140mm Noctua as an intake to see what that will do.

I attempted to bump up my CPU to 4.7 and it crashed; however my gut says you can't just adjust the clock, you have to do more than that yeah? Meaning, stop relying on the auto tune crap and go learn what the hell I'm doing before I blow it up? Any quick start/newbie guides you recommend that aren't lengthy? ie. cliff notes for dummies?

Another question. My Phanteks Enthoo Luxe has a PWM fan hub that supports 8 fans. I have one single, 3 pin 200mm Phanteks fan connected. When looking both in Bios and AI Suite, this fan is not registered. Is this because it's a 3pin fan? I thought the PWM hub would handle this? I like being able to see the RPM per fan and being able to adjust these ... should I be seeking a new 200mm fan and/or moving to dual 140's?

Sorry, I know I'm all over the board here, but lots to do still.

Thanks!

Hey all,

I just used OCCT to stress test. Once I hit 100%, I remained there for about 4 minutes until I crashed.

Core 0 was running at 80; whereas the rest were between 65 and 75.

Is this normal/expected? I fear that either A) my OC is wrong (I used ASUS AI Suite to auto-tune) and/or B) I screwed up somehow with the Swiftech H-240x install? The simple fact that I idle in the high 30's with very little activity occurring, makes me nervous.

Thoughts?

Also, shouldn't have my CPU fans spun faster as the temps increased? They never did ...

Further, should I be thinking about replacing the Swiftech Helix fans and/or adding a third for a partial push/pull?

Thanks

If the program crashed your Overclock or the way you mounted your CPU is wrong.
I suggest you read some guides on how to overclock 2011 cpus and listen to their advice.
Do not rely on Automatic Overclocking software.
