Hi All,

I wondered if you could give me some advice on my recent build I done. I have got an Intel Core i5-4670K @3.4GHz cooled by a Corsair Hydro H60 heat sink. If I was to run a game such as CS:GO my temperatures will peak to around 69/70c. This is a worry as I have not tampered with the clock speed what so ever. It is still running at the default speed of 3.4GHz.

I have read articles and spoken to friends and it seems like the Haswell chips are hotter than most others but this to me seems a little too high.

I have also looked into de lidding the chip. Is it worth waiting at other possibly solutions before I try this.

Thanks,
Zak
 
Don't delid for non-OC temps.

What kind of case, and case cooling do you have?

Did you apply the cooler correctly?

You could try undervolting it a bit. Check what kind of volts it needs on load at stock, and we'll go from there.
 
I have the NZXT Enthusiast case. It has 3 fans on the case excluding the fan on the heatsink. I have checked the heatsink is sitting on it correctly too.

I want to overclock the chip which is why I got the overclock able version but I just want to make sure the current temps are ok before I do overclock.

When the PC is idle it sits at around 30-40.

Would it be worth putting fresh/better paste on as I am using the default spread.

Thanks for your replies.

Hi Zak, i have one of these CPUs and have clocked mine to 4.2Ghz and this is with a cheap £12 Alpenföhn cooler - Idle i get the same temps as you, and in say playing BF3 get around 75 to 79 degrees - I am awaiting a NH-U12S Ultra-Quiet Slim CPU Cooler with NF-F12 Fan and ill post my temps with this on in a day or so but i have read these temps are ok for this CPU, i just personaly dont want it that hot if i can avoid it :D
 
What GPU do you have?
I though your case came with 3x 120mm & 1x 200mm fans?? What positions do you have your fan; which are intake and which exhaust.

Jonny thanks for your response. The temps are definitely higher then what they should ideally be. I have tried re seating this multiple times. I will take another look and get back to you soon. I think the issue may be because of the thick tubing on the cooler possibly lifting it away from the CPU. Even though it is screwed down I feel it may be lifting away slightly.

doyll I have a NVidia GTX 660 OC. Also one of those 120mm fans is one I had to attach the radiator to for the cooler. I put another fan on the inside of the radiator for better cooling making sure they are in the correct direction.

Your help is much appreciated. I will get back to you on reseating the cooler
Thanks,
Zak
 
update with the new cooler

As mentioned above i now have my new CPU cooler in place and WOW! - I am getting 29 to 33 on idle and on BF3 no more than 55, this use to be near 80 on my old cooler. If you have the money i would def reccomend getting one of these NH-U12S Ultra-Quiet Slim CPU Cooler with NF-F12 - i am so pleased and its so much quieter to :D

I used the thermal past supplied with the cooler to so no need to worry about getting a good past, this seems to work fine.
 
Nice job Jonnyb. Those temps are great!

Zak, your GTX 660 is about 150w TDP which is a little more heat than our CPU makes when you are gaming.

As I asked before;
What positions do you have your fans; which are intake and which exhaust?

I'm guessing your H60 is mounted on back exhaust so heated air from GTX 660 is pre-heating the air going to H60.

We want more airflow through case (cfm) than the GPU and CPU fans move.. We need to be sure the GPU and CPU heated exhaust air is not mixing with the cool intake air being provided by the intake fans.

It all depends on how well you keep the heated exhaust air from CPU & GPU coolers from mixing with cool air going into coolers. A cheap digital indoor/outdoor thermometer and a little time testing will let you know what's what. The below might be of interest too.
The only way to know what works best in your case (no pun) is test different combinations and see.

There is much more to cooling than good cases, good fans and good CPU / GPU coolers. Modern GPU's make more heat than CPU... and getting that heat out of the case can be a challenge.

Setting up the case to cool properly is the hardest and most time consuming part of a build... And the most neglected by most builders.

Cases, especially those with filters, usually benefit from fans with higher static pressure ratings than stock fans... "cooler" fans instead of "case" fans.

Intakes are typically more restricted than exhaust; air filter, more restrictive grill, HDD cage, etc. I prefer a little more intake than exhaust.

And don't confuse number of fans with amount of airflow... or cofuse airflow with airblow

Airflow is flowing cool air from intake to component and flowing hot air from component out of case without the hot air mixing with the cool air.

Airblow is lots of fans blowing air with some of hot air from components mixing with cool air making it warmer resulting in warm air not cooling components as well as the cool air will.

Putting fans in case as intake and/or exhaust is only the first step. These fans only move air in and out of case.

This does not mean heated air is not mixing with cool air.

Nor does it mean cool air is going to where it is needed.

Getting the air to flow inside of case properly is even more important. We still need to manage where the air flows inside the case. We can do this several ways; deflectors, cooler intake fans, exhaust fans, removing vent grills, using fans with higher pressure/airflow, building ducts to or from CPU/GPU cooler, etc.

Using a remote temperature sensor to monitor what air temps are is the key to finding out where the cool air is flowing and knowing heated air is not mixing into it. By monitoring this we can than make changes to get airflow the way we want it.

I monitor the temps with a cheap indoor/outdoor wired remote or terrarium digital thermometer. Twist a piece of stiff insulated wire into the last 8" of sensor lead so you can bend it to position sensor where you want it... like 40mm in front of your GPU cooler/radiator intake.. to see what the air temp going into CPU / GPU cooler is compared to room temp. The closer it is to room temp the better.. Shouldn't be more 5c maximum, 2-3c is what I usually end up with after 30 minutes full load on both CPU and GPU.

Hi Guys. Sorry for not getting back to you as I have been a bit busy recently. I will take a look at my PC soon for intake fans and so on. I may upload an image of the PC and label the fan positions etc if that will be best.

Thanks,
Zak
 
Hi guys. Yesterday I got some thermal paste remover and some new thermal paste. I am pretty sure it is the CPU cooler no sitting on the CPU correctly and when I put the cooler on and then brought it back off there was at least quarter of the CPU that didn't have any thermal paste applied. I can fit a piece of paper underneath that side of the CPU which is a bit worrying. Any suggestions?

I think it may be the clamp to hold down the CPU that is preventing the cooler from getting to every part of the CPU as I have taken the CPU out and just applied it to the bottom of the cooler and it covers all of it.

Thanks again guys.
 
Hi All. With a fair bit of investigating I think I have resolved the issue. This seems odd to me as the cooler has a flat surface along with the CPU. But all I done was switched which way round I had the cooler and it is now making more contact with the CPU. I have removed the paste and added it on again.

I run Prim95 for 10 minutes and its max was 80c. Would you say this is now about right for a haswell CPU?

Thanks,
Zak
 
how did you apply the thermal paste? i smeared mine on till the surface was covered, but my friend said all he did was apply a pea size and put the cooler straight on without spreading?
 
I find that if you have stiff TIM, it is easier to get better results by spreading it using a card. Thinner TIM spreads better by just applying it with a blob or a cross method and letting it spread out when you apply the cooler. Putting too much will increase your temps as much as putting too little.
 
mine was real stiff, was a pain in the arse tbh lol 1st time doing it.......my temps dont go above 40oC for my general use and max 76oC in prime95 so must have done a half decent job :)
 
Zak, if it helps I'm running same combo of a H60 in an NZXT Enthusiast case, my CPU when not overclocked would sit at 42 under load, make sure you fan on the rad is plugged in and working. I let mine sit at 70% so that its not too noisy. Your temps aren't an issue but I personally would like em down a bit so that you have room to play with :)
