Questions regarding 4790K

Hello,

I have just bought a 4790K, It's not installed yet, waiting on RAM but I want to get prepared a little. I have heard that this chip runs quite hot, so I would like to find out your opinions on the following;

I have bought an Arctic Cooling Freezer 7 Pro for it. Will this be enough?

This cooler comes with factory fitted mx-2 thermal compound, should I remove and apply my own MX-2 or leave the factory fitted?

I would like to OC in the future but im sure going from an E8500 to this will be enough for now.

Thanks in Advance!

*edit

I now after being told how hot this chip is going to run have turned to the following;

"okay, so scratch the OC. I have changed my mind to wanting low temps at stock speed, on air. Budget of 60£ for the cooler"

The cooler should be 'enough', but I don't think you should expect any overclocking headroom using it.

Comparing it to the stock cooler referenced in the old reviews, I'd say you'll see high 80's, maybe 90's at full load, so pretty hot.
 
Yeah the Freezer 7 should give you better temps at stock but dont expect it to cope with an overclock. I use the BeQuiet Slim and that is fine at 4.5Ghz all cores under load with temps around the 80Degree mark.
 
Did you just buy the Arctic?

To be honest you'd be better off returning it and using the money towards a better cooler.
 
What cooler would you recommend if i wanted to OC to say 4.8? I'm a little out of touch with cooling gear these days, is it worth getting a cpu watercooling kit?
 
I have only looked into low profile and compact coolers, as I have a mITX with not a lot of space.
Could have gone AIO watercooler easily, and that is what many would do... but I don't feel 'ready' for these units. Wether that is a good solution for you depends on your case: can you fit the radiator.
I settled for Noctua NH-U9S, but in a normal case you can get a much bigger, more effective cooler.

Post your case and people will be able to suggest you something!
 
I have a XCLIO A380 that i bought when i was 14 lol.

Also if i do choose to stick with the freezer 7 pro for a bit untill i decide what to do, should I use the factory thermal past on the 7pro or apply my own?
 
I depends how much you want to spend on top of the Freezer Pro. For an extra 10-15 quid you should be able to get something like the BeQuiet Pure Rock, Raijintek Themis Evo or even a monster one like the Raijintek EreBoss, Prolimatech 81 or Akasa AK-CC4008HP01 Venom Voodoo.

I will say though that if you are attempting to get 4.8Ghz you will almost certainly need custom water for 24/7.

If you want to use the freezer 7 pro for a bit just use the standard thermal compound as its usually their arctic MX and is very good for the money.

Noctua NH-D14 Dual Radiator CPU Cooler. £6 higher, very big.


I would go with a slightly smaller one which is Prolimatech Black Megahalems CPU Cooler. This one is very good, easy to assembly. 8Pack uses it daily as well. I got my i7 5820K @ 4.5Ghz with this as well.
 
That certainly doesn't look like any old case ;-). Should be plenty big for the biggest of air coolers, assuming they fit the boards components!

@Craiig: You should be able to get decent temps and OC some with the coolers mentioned.
 
Sorry to keep this thread going, but i have now looked into getting this as im sure this should fit in my case.

Would this be sufficient? for my new 4790k? :)
 
Okay, so at the moment I think ill go for the NH-D14. However, would the Corsair Hydro H80i provide better temps? also would this option be quieter?
 
I have the top-dog Noctua that was around before the NH-D14 came out, but if I was buying new now I'd probably go for a Corsair H90 or the like. The water coolers tend to have lower temperatures and also means you can get away with having one less fan in your case, so it'd be quieter. Costs a bit more though, so swings and roundabouts.
 
I can't comment directly on the H80i but I have an H75 on my 4790K which is lower spec than the H80i and my cpu gets to about 74 degrees under extended handbrake encoding when overclocked to 4.6.
 
AIO's are generally louder and hotter than the best air cooled options, for the CPU alone. However, they are not massive and heavy on the mobo and dump their heat out of the case. I'd take a good air cooler over an H80i any day, unless building in a case that prevented the use of a big air cooler.

Watercooling's advantage is taking the heat from the CPU to the radiator and as they can be located elsewhere it allows them to be large. The water itself makes no difference, it's just a mechanism to move the heat, not to dissipate it - exactly like the heatpipes in air coolers but easier to route over greater distances and have bends in etc. The radiators are the key (or, if you're using a chiller, the chiller matters lots too). The disadvantage is that the pump adds noise.

Note: this is talking about steady-state where our temperature is governed by how quickly we can dissipate the heat to the surrounding air, regardless of if using air or water cooling. For brief spurts the WC will hold an advantage due to the specific heat capacity of the water itself, keeping the temperatures from rising as fast. In reverse, the WC system will take longer to cool down if there is a sudden drop, for the same reason.
