Intel i5 3570k - need opinion on this

Hello guys,
This seems like a nice serious community, and i wanted your opinion on this.
So, i upgraded my computer a week ago, my current setup is this:
CPU: Intel i5 3570k
CPU Cooler: Noctua NH-D14
Motherboard: Asus P8Z-77 -v LX2
Samsung 840 (128gb) SSD
HDD: Raid (Seagate Barracuda X2)
PSU: Seasonic 750w
Ram: Kingston HyperX 1600mhz cl9 DDR3 4x2gb
GPU: Asus Radeon HD7850 (i get a second one in a week)
Tower: Corsair R300

I assembled the computer myself, here is a picture (i put a lot of effort into cable management, the cables stuffed below the HDD's are there temporarly because i am waiting on more hardware):
http://i39.tinypic.com/29qb0g9.jpg
Note: the CPU fans are blowing towards the rear fan which blows outside the case, the front one sucks air into the case, the PSU is mounted so it blows out of the case, through the bottom filter thing.
I moved my pc from under the table to a more open area so that it has better air cycling and less dust.
I overclocked my cpu to 4.2Ghz (3.4 standard) and 1.3V.
So, when running really hardware demanding programs or games, i get high cpu temps of over 60c, the gpu reaches a maximum of 50-55c so i'm not worried about it, my main question is if my cpu should stay overclocked and keep running under these tempertures or my cooling is enough to keep it this way.
Idle temps: 33-40c (core1 gets the highest score while the other ones stay 4-5c below it).

Also i have one rear 120mm fan, one front (the middle slot, not the bottom one next to the hdd's) 140mm.
I am going to get two Scythe Gentle Typhoon 1600rpm's (might go for the lower ones actually if this will be too loud) for the top of the case.

TL:DR:
you have my specs, the way i built it, and a picture, here is a picture of a benchmark i ran with FluidMark, am i doing ok?
Benchmark: http://i43.tinypic.com/etbcjp.jpg

Thank you very much and please give me some tips on how to optimize my build, what can i add to improve cooling and airflow, everything.
David.

60c is not at all high for a 3570k, keep going till you get to 80c or even 85c. Stay around that and youre golden.

By the way do you really require 1.3v for 4.2ghz? Thats quite high for 4.2 you can probably get more outa that. I get 4.5ghz out of 1.3v and mine is a mediocre chip, others can 4.5 out of just 1.2v.

Hello Bluemustang, thanks for the fast reply.
Isn't 80-85c way above the standard temps? wouldn't that mean shortening the life of my cpu? i want to optimize what i currently have to the highest level it could get while not damaging anything and keeping it as safe as possible for the cpu.
By the way, with that massive cooler on my 7850 i overclocked it to 1200mhz (max the asus program lets me) with max of 65c, would it be ok to go for more?

85C is actually way under, the thermal threshold as stated by intel is actually 100C (actually it might be 105c i forget precisely, but its definitely at least 100). But thats the point at which damage starts to occur, 85c is the highest safe constant temp. If it was an amd cpu that temp threshold would be much lower though.

You can go a bit further on the gpu, keep it below 80 preferably 75.

For testing cpu temps use prime95, for testing gpu temps use harsh games like crysis 3 or unigine heaven/valley benchmark. Don't touch furmark/kombustor/occt.

PS: While the cpu is safe up to 85c youre closing in on the voltage limit, dont take it above 1.4v. Personally i wouldnt go above 1.35.

Hi,
i listened to your advice, the reason i had 1.3+ volts are because i had vcore set on auto, i dont know why it did that.
i set it up manually to 1.26, after some blue screens and playing with it this is what i reached.
btw i used prime95.

please advice me where can i go with it now, can i safely continue to overclock?

btw, i looked into how to de-lid my cpu, as it is ivy bridge and i understand it has crappy thermal paste instead of the older thing the used that worked good.
how much will this really help my cpu? is it worth it? if i am going to do it i am gonna research the crap out of it, but for now, with my air cooling (and not so extreme setup), is it worth it?

I already told you that you could go to 85c and 1.35-1.4v vcore, which that isnt at. But dont use speedfan to read temps use coretemp/realtemp.
 
#7 ·
aight, using coretemp now, ill leave prime to rape the cpu a bit more, if it comes out that it IS stable for about 3-4 hours, ill overclock it further.

also, the two fans that i want to add in the top, supposing ill put them so that they suck air into the case, ontop of the cpu cooler, would that help?

how would it keep dust out? sorry for asking i just didnt understand you, please explain me !

1. DO NOT have top fans as exhaust, or they will steal your CPU cooling potential.

Let's say you only have exhaust fans (or more than intake fans) you have something called negative something (can't remember what, I don't have english as primary language + still a young student. Might be pressure). If you have negative pressure, basically your case will become a vacuum cleaner, sucking air thru all holes in your case. On the other hand if you have positive pressure, all dust coming from the intake ones will come out from the exhaust one.
My fan setup is like this: 3 intake fans in the front and one exhaust in the back of the case. My temps were best this way.

There's a good reason as to why every case manufacturer who ships their cases with top fans points them out, because hot air rises. Obviously the method I described works best if every fan hole is filled, but you're fighting gravity by pushing air in through the top. The idea of the fans is to create routes for the air to travel, and you want cooler air to come in underneath your hottest components (CPU, GPU) and have the exhausts above or behind them.

Pushing air down vs. up is like pushing something uphill vs. downhill: yes, it will move where you push it, but in one case you're facilitated by the air's natural tendencies thus increasing efficiency. Also, the fans on that heatsink will have no problem pulling fresher air from the front of the case. Also, if you have too many fans pointing in and not out, you will have too much static pressure and then have trouble venting all of the hot air from the case.

ok so im confused, right now my front one pulls air inside, the rear one pushes air out, the cpu cooler pushes air towards the rear.
the most reasonable thing i see here is put both of the fans im getting on top so that they pull air into the case, and the 3rd one in the front for intake too, so basically i'll have 4 fans pulling air inside, one rear as exhaust and the psu which is faced downward so that it pushes hot air that goes through it outside the case.

am i doing something wrong?
also the see-through door on the case (in front of the motherboard, not behind it) has two places for fans, but since the cooler is so big i could probably only put one 120 mm on the one closer to the front.

Front/side as intake, rear/top exhaust.
 
#19 ·
In my mind, i cant imagine it would make much difference. You've got the fan directly on the heatsink pushing air through it with good static pressure to the rear exhaust fan just a few inches from the heatsink. The top fan should be even further away from the heatsink and it couldnt possibly compete much with those speeds/pressures.

Either way from the little it may be stealing from the rear exhaust its still expelling that air after air moving strongly across the fins.

TBH just make sure you have positive air pressure, the orientation can sometimes mess up and give you a hotter case so do some testing with real temp GT and msi afterburner or whatever gpu overclocking temp monitor program.

That's what I did, On my case (650D, crap for air cooling lol I knew that when I bought it anyway), Having one 200m intake at the front, one 120mm at the rear as intake and one 200mm at the top as exhaust, made my temps alot better than having 2 exhaust and one intake.

Test around and then you'll be okay.

I have 2 fans in push/pull on my antec 920 (radiator located at rear 120mm) and they are intake as I want the coolest air going through my rad. I have 2 front 120mm as intake and 2 140mm top mounted as exhaust. With my Lancool PC-K62 case this config gives me the best cooling. I don't too much for dust as I regularly clean my PC and radiator. Just my

Hello, thanks for all the comments, what i made of them was this, the red/white arrows represent what i currently have, the blue arrows are what i intend to add (3 140mm fans), here is the picture:


Also, when overclocking with asus uefi bios, i noticed that the core voltage i set is higher then what i ACTUALLY get, in the uefi i am currently on 1.30v but each monitoring program shows me around 1.26v at load. another thing, on full load (prime95 torture test) i am currently on 100% cpu 66-68c 1.248v BUT! right before i started it i noticed that while idling i get 1.3v, why is this happening?

Since that gpu doesnt appear to be rear exhaust you might think about sticking an exhaust fan beneath the gpu to handle the air coming from the hdd area and gpu heat to avoid hot pockets before the heat rises to the hard to get to top exhausts. Just add up the CFM all the fans (i wouldnt include the psu as its rather confined to itself) and just make sure the intake is a little higher.

And your voltage drop is normal, thats called vdroop.

just what i was thinking i already ordered a pci fan to send all the heat to the rear, question: when i get my 2nd gpu, will the front fan be enough to send the heat that is generated between both the gpus to the rear?

about the voltage, thanks, i didnt think it will be that high

what about the top fans? what do you think?

Well i didnt mean a PCI fan, that just moves air onto the card which is pointless. I meant a regular old 120mm or whatever fan placed beneath the gpu to exhaust air from that area out the expansion slot area. Since that area having the big gpu makes a bit of a hot pocket with the air a bit hard to move to the top for removal. Remove the expansion covers if theyre not mesh. But if you get a second gpu thats probably not possible.
