Hi

I'm new to this forum, but I'm really hoping for some advice.

I have an i7 4700k, 8gb DDR3 Corsair Vengeance, Hyper 212 Evo, 120GB SSD, Asus GTX 780, Zalman Z11+ case. Gigabyte z87x-d3h motherboard.

Basically I'm running it overclocked to 4.4ghz on 1.140 vcore, everything else is set to auto. It seems to be stable (no crashes running prime, intel burn test and aida64). My main concern is that temps are max 80-85c at flatout and the system idles temps of 30-40c.

I can get 4.6ghz relatively stable on 1.20 (tested for a few hours no crashes), but the temps were too close to 90 full load, pretty much the same with 4.5ghz.

Also, I've applied/reapplied Arctic mx-4 paste a number of times and I think I have it as cool as it is gonna get.

Basically I'm happy how it is, I'm just a little concerned leaving the vcore so low with temps a little high, whether this will damage anything long term.

Any help appreciated. I was thinking of getting another fan for the Hyper 212 and try push/pull.

Cheers
 
Haswell are pretty hot chips anyways (because of the crap way that Intel stuck the IHS to the CPU assembly). Temps sound maybe a little on the high side given the vCore but IIRC, Haswell doesn't start thermal throttling until it hits 100C. I think your usage of the 4770K will far outlast it's life, even given the overclock.
 
The EVO coolers are good budget coolers, but haswell needs something that's a little better. 90 is a little on the high side, but it shouldn't cause any major problems. If I were you though I'd keep an eye on the temps.
 
Thank you both. I've decided to stick with the 4.4ghz at 1.140vcore

I was considering the H80i water cooler, but having a quick google around I'm only noticing a slight difference in temperatures to what I'm currently getting at this setup - so I'm a little reluctant to fork out another £70 :rolleyes:. As much as I'd like the H100i I don't think it'll fit in my case.
 
Thanks for your input folks. I'm going to grab a couple of 120mm fans on Amazon first and give the push/pull method a go and then look into these other options.

Some of the other air coolers I don't think will fit with my Corsair Vengeance Ram as they have the high fins, that was why I went with the Evo first.
 
I'm gonna go with a noctua cooler in the near future/summer and partex my vengeance ram for some low profile ram.

I put another fan on the Evo 212 so it's now push/pull and added another exhaust fan on top and it's dropped my temps by a good 4-5c. Cost me £15 for the upgrade. Happy for now.

Thanks again everyone for the input, put my mind at ease.
 
Team group is indeed very good ram, running the kit in sig at 2600mhz, 11-13-12-31, 1T. Its rated for 2400mhz, 10-11-11-31, 2T.

Low profile so fits below my k2 easily, (great cooler btw). Temp wise, on haswell just dont bother with synthetic stress tests. Theyre cpu killers and youll never see temps that high in normal use.
 
you got roughly the same v as i need for 4.4 on my 3770k, got a very good chip there indeed, but I wouldn't of thought you'd be reaching that high temp at max load, that seems too much to me, unless the airflow in your case is restricted.

I'm now getting about 27-33 under normal operation, surfing, downloading etc. Gaming I'm reaching about 65-70 running 1080p maxed out. It doesn't seem to go any higher temperature wise even running multiple apps/renders etc.

I also gave it a good 5 hour Battlefield 4 session last night - for a real test ;)

Sounds like you're set then, since you seem to have done well in the Haswell Heat Lottery, may I suggest a Euromillions ticket tonight?
 
Hey mattnotts86

May I ask how you overclocked?. Just received the same mobo/CPU, and was reading about the two methods of overclocking, old style, and energy efficient with a fixed voltage. Did you just up the multiplyer? or did you need to engage in some bios jiggery pokery?
 
Exactly as you described. Increasing the vcore and multiplier and booting up and running stability tests. I didn't fiddle with anything else. I did find, however, that stability issues have started to creep in over the past few weeks so I've had to up my vcore to 1.20. I get around 35-40c temps and at full load nothing more 80c.

I've since looked in better cooling options and another case, so I'm thinking of seeing if I can push it further and increase the vcore a tad.

What method did you use to apply the paste? I have been converted from the spread method to the pea/rice method after seeing a ~4c drop when trying both methods on the same cooler with the same paste.

I tried both a total of 4 times and I didn't really notice much of a difference with the Hyper Evo 212. All stayed around the same temperatures.

It's currently running on paste applied using the pea method with MX-4 paste.
