hello! i recently aqquired the noctua nh-u14s cpu cooler.i have the intel i5 4670 and i had the stock cooler .Before i put the noctua cooler i made some tests to compare the cpu temps..at idle load, the stock cooler was at around 33-35c and at full load 70-73c.. with the noctua cooler the idle tempratures are the same and at full load are 59-60 but i can hear the fan working a lot plus the general noise of the noctua is bigger than the stock cooler....is that temps (at high load) are good for tha cooler?? (my build is gpu asus gtx 760 direct cu2top ram 2x4 gb teamgroup psu 700watt thermaltake toughpower)

P.S are those temps going to drop in winter because of the lower room temprature?

To start with, it matters greatly what the ambient temperature is in the room where the computer is. That will affect what your idle temps are going to be. As far as your load temps, if that is at 100% CPU load, after about fifteen minutes at that load, then they are fine.

Your cooler should NOT however be louder than the stock cooler. It should be MUCH quieter at idle and moderate speeds and MIGHT be louder at full speed but should probably not ever run at full speed unless you're running a thermal testing utility like Prime95 or something else that loads the CPU to 100%. In normal use you'll probably rarely encounter that.

It's always possible that you used the wrong amount of thermal paste. The tutorial at the following link...

It's always possible that you used the wrong amount of thermal paste. The tutorial at the following link outlines how much thermal paste should be applied, and how, although it's for the 212 EVO the procedure should be identical. I have the NH-U14S on my rig as well and am very familiar with it. I think it's extremely likely you either don't have enough case fans or did not paste correctly if your cooler is loud during normal use. Your CPU cooler can only work as well as the amount of cool air it has to work with and it only has enough cool air to work with if the case cooling, by way of intake and exhaust fans, is sufficient.

My rig with the NH-U14S and some cooling modifications:

And if the temps in the room are lower during the winter, then yes, the idle temps will probably be lower as well at that time but a lot depends on how much actual airflow through the case you have. If temps are an issue you may need to fill any unpopulated case fan locations or make sure all case fans are correctly oriented. Front and bottom fans should be intake. Rear and top fans should be exhaust, unless you have a top mounted power supply in which case the configuration will be a little different.

thank you for your answer! in my case i have 2 fans one in front intake and one at the rear exhaust. i had the same fans for the stock cooler. i think you are right about the thermal paste because it took me several times to screw the cooler to the base and each time i put and the i lifted the cooler so the thermal paste may got lesser..i surely screw the cooler very well so i guess i m gonna have to apply the paste again...but should't i have to get higher temps if the thermal paste was wrong??

I doubt that paste alone is your issue. If those temps were at 100% CPU usage while running a stress utility then they were probably ok. If those were temps during normal use, they are too high. Better temps will be achieved by adding additional case fans.

Your temps are acceptable but don't seem typical of that cooler paired with an i5, the fact that it is louder is a key indicator that something is amiss. As Dark has said, improper themalpaste application can be a factor in this. When you remove and reapply your cooler without reapplying thermal compound it isn't so much that the quantity of paste diminishes, but rather that you can create tiny air pockets between your cooler and processor which will drastically diminish thermal efficiency. I srongly believe that improper ventilation could also be a factor here.

I've read through this thread a couple times now but I don't see what case you have Stevi. What case you have will help us determine your proper fan orientation and further troubleshoot where your thermal issues are coming from.

those temps were at full cpu load....my case is several years old for atx mothermoards...here are some fotos... because i dont know the make of the case

I noticed this very strange thing just now! when i removed the side cover of the case the cooler even at full load is quite! i checked wheather the side cover was touching the cooler but no! i think that because the cooler is big and my case isn't, the generated air from the cooler "hits" the side cover and i have this noise.... (just my theory!) but based on what you have said i think my temps are ok..

P.S IamTimTech why do you say that is not typical for this cooler to be paired with an i5? is it because my i5 dosent support overclockig so there is no big need for such a good cooler??

You misunderstand my friend I was saying that the temperatures you are seeing are very unusual for an I5 paired with that cooler. Not that the cooler CPU combo is uncommon.

Cable management, you need cable management. That will be step one. Those cables should be tucked out of the way in tight coils allowing for free flow of air through the case. The sound you hear is the air wooshing around and through that cluster of cables. Reapply your thermal paste as mentioned by Dark and then manage those cables and I bet your problem will be fixed.

Edit: In the future you may want to consider a newer case. Your system is a nice setup, but the case does not look thermally efficient at all......OR you could break out a drill and a dremel and have some fun with it lol.

i see.. you're right, i think i have to do that... what to you think the right temps(on full load) sholud be for this cpu and cooler?

i'll keep that in mind! i have had many upgrades with tha case! if you noticed from the sticker in front i have had a brand new amd athlonx64 when i bought the case! pfff we're talking about 7 maybe more years ago...

The small case fan in the back probably doesn't help either.

I have been wrong before and I could be wrong again but I think that fan is a 120mm, but if you are right it is a 90mm and they tend to be loud. Also he said his noise levels were fine before with the stock cooler so I am not sure that that is the source of noise (though it totally could be one too).

So, the fact that temps and fan speeds instantly dropped when you removed the side panel is all the fact based reinforcement I require to positively say that case airflow is the problem Run the unit with the side panel off until you can replace the case. The fact that you have a top mounted power supply doubles the problem with that case having

1. Very small fans and not many of them.

2. Poor ability for any cable management.

3. No possible way to vent the heat that rises to the top except through the already hot power supply, which will also have the added wonderful benefit of killing your power supply much faster as well since it too can not catch a break when it tries to cool off.


Get a new case. Run without the side panel until you can get a new case. Those old style cases were never intended to be used with todays modern hardware that use much more power and runs much hotter than hardware from years back.

Find a mid tower ATX case you can afford, or save for, with at least two front intake fans, a rear exhaust and at least one top exhaust, preferably two top exhausts. And make sure it has a bottom mounted PSU location. You do not want a model with any fan location sizes smaller than 120mm and preferably all at 140mm. 120mm rear exhaust is ok if there are also top exhaust locations.

If and when you can budget for another case, let me know and I'll recommend a few really good options if you give me the budget you might be able to or can, afford.

1)do you think with a 100euro budget i could get a case like that you described?
2) with a new case that meets those criteria the cpu temps will be the same as now excpept the noise, or will further drop because of the better air ventilation?
3)what will i gain if the psu is at the bottom? it will still push hot air upwards to the case...

Read reviews because you're the only one who knows how quiet you want your system to be: http://www.tomshardware.com/reviews/corsair-obsidian-550d-fractal-design-define-r4-gigabyte-luxo-m10,3356.html The Fractal Design R4 is a very good case, but it may not meet your own tastes and requirements. The CPU temperature shouldn't be higher, but you won't hear the fan. A PSU at the bottom draws air from under the case (the reason for the filter) and it pushes it outside of the case, not in the case.

1) Yes! You certainly can. Any of these cases are excellent choices and there are even more out there: http://uk.pcpartpicker.com/parts/compare/corsair-case-200r%2Ccorsair-case-cc9011049ww%2Cnzxt-case-cah440wm1%2Cphanteks-case-phes614pbk/

2) Yes with a new case, cable management and a few new fans to populate all of your front, rear and top exhaust ports your temps should get rather frosty as long as your room's ambient temperature is good.

3) As Dark mentioned above; heat rises. So in a system with the power supply on top it catches all of the hot air and spends it's whole life breathing hot air, which in turn may shorten its life. This isn't exactly a death sentence with proper ventilation and good ambient air temperatures, but bottom mounted power supplies are preferable and all of the cases I just recommended are bottom mounted.


Edit: Of all the cases I recommended above the Enthoo Pro is my favorite. Great craftsmanship from those Phanteks guys, and along the lines of craftsmanship the Fractal R5 is such a quiet and well built case too I have personal experience with it and I loved it. The only draw is that it is very subtle, not flashy at all but a lot of people really like that. The 200R is an excellent budget case with everything we've described without some of the other features that cost more. And lastly the NZXT 440 is a great looker and a very popular case. I just don't have any personal experience with it.

There's nothing wrong with the Enthoo Pro for building a quiet system. I've used the case for several builds, which were dead silent. The Phanteks fans are very quiet and adding additional high quality fans that are also silent just helps to keep it that way.


For your price range though, I'd probably go with the Corsair 300R and add a few high quality 140mm fans to populate any unpopulated case fan locations.

The issue isn't just the fans. The issue is the restrictive airflow in that old gigabyte case. More cooling is always better.

I hear what you're saying, some prefer cooling, some prefer silence. People like me have both. In any case, any case he chooses + a couple of 120/14mm fans will provide excellent cooling probably be much quieter than his current case

thank you all for your immediate answers! i will look into your suggestions and make a little search of my own to decide which one i'll choose... one last question before we close this topic...my motherboard has 3 connectrors for system fans.if i choose a case that has pre-installed 2 fans those 2 fans would draw power from those connectors, leaving me space for one more fan or they would draw via a molex connector?leaving me space to put another 3 fans??(if it helps i liked Corsair Carbide 300R Gaming Midi Tower http:// )

That's what people who have never had a system with excellent cooling always say. Cars don't need three core radiators either, but those that have them tend to not ever overheat even when issues develop, or at least less frequently and to a lesser degree, last longer and more efficiently regulate temperatures than identical engines with single or dual core radiators. More IS better. Plus, it makes no sense to make a major hardware purchase that is ONLY good enough for what you have now. Future hardware upgrades, for example, to a chip or GPU that CAN be overclocked, may very well find it advantageous to have the increased airflow from a good case and additional fans.

There are plenty of rigs that are not overclocked that still run close to the higher end of the temperature spectrum, that will definitely have a much longer lifespan if the hardware is run at temperatures closer to ambient, say 45-50°C under load, than one that is constantly running at 60-65°C under load. Cooler is always better. Period. It might not be "strictly" necessary, but it's always better. You can run a system on the stock cooling in most cases, but it doesn't mean it's going to have a long lifespan, be nearly as quiet or run anywhere near as cool.

I agree that there are lower end cases that will offer "sufficient" cooling, but considering what the OP outlined as the budget for the upgrade, a nice case with good features and a couple of additional fans is a certain method of insuring that he'll probably never need to replace it again anytime in the foreseeable future regardless of what hardware upgrades may occur at any point.

You can connect as many fans as necessary. You might just need to get a couple of these and use two fans per header:

http://www.newegg.com/Product/Product.aspx?Item=N82E16812162026


The cases that have been suggested here aren't what's important. What IS important is that it be a case with a bottom mounted PSU bay, and at the very minimum, and I mean absolute minimum, one front 120mm fan, one rear 120mm fan and one top 120mm fan. Additional front, top or side fan locations are just extra insurance and offer room for expansion at the least. At the best, having 140mm fan locations will provide quieter operation when 140mm fans are used as well as provide an increased airflow, as will having the additional front and top locations for a total of at least two front, two top and one rear location.

Cases with only a single front 120mm fan and a single rear 120mm fan only exchange at a rate of about 65% of the internal case air per second. Two 120mm exhaust fans and two 120mm intake fans will exchange about 125%. Three 120mm exhaust fans and two 120mm intake fans about 160%. And so on. Those figures are not exacting and are of course subject to a variety of other factors such as case design, cable management, fan model, fan profile settings, etc. But it's close enough for the sake of argument.


With every single component inside the case creating heat, the closer you get to ambient temperatures of the room, the better off your hardware is. Anything contrary to that is not an arguable statement.
