Worried about my Haswell temps Advice Please!

Well that is very high. Have you tired using another software?

i highly doubt those are your temps with a working 212... maybe try testing your temps with a different software? How is your 212 running? Maybe your processor or cooler is deffective .

99c. is worrisome if accurate.
If you are not overclocking, your cooler mount is probably bad.
Try using occt for oc stress test.
I found it to be a better test.
It will stop the test once you reach 85c.
Your overclock is probably too high. But it is good that you are not failing.
The cpu should downclock the multiplier if the temperature exceeds a safe level.
The temperatures get very high when the voltage goes over 1.3v.
If you are using one of the automated overclocking methods, it is likely too aggressive.
Try just raising the multiplier gradually from the default 35 and see where the temperatures start o rise rapidly.
How well you can oc is mostly determined by luck of the bin and a good chip.

Yea vcore is the voltage of your cpu. Wow, well if it says error and runs on minimum only, then the 212 is deffective. RMA it bro. It should run around 1800RPM max.

You can also look to do what most are doing with Hasfire, delid it and repaste it with high end thermal grease, that will give you around 20% lower temperatures notably at load the downside is you lose warranty.

it's obvious that the problem is your 212... listen to what retiredchief said (he seems very knowledgeable ) and the others. If you can't get it working return it as soon as possible! On another note, if you do end up returning it for a refund it may be worth your while to get some corsair hydro series liquid cooling setup for an extra 20-30+ $. Best of luck

Closed loop liquid cooling doesn't much offer cooling compared to hyper 212. Just about 2 to 3 degs.. Not worth the money, IMHO.

I still love my h80i that i bought for 80$ on sale. I think 2-3 degrees is a little bit of an understatement but i'm not here to argue

The hyper 212 is for only $33 at newegg now. Though I have nothing against CLLC...... It's just that I love my hyper 212 so much. lol Not here to argue too :*

the 212 offers great performance for its price from what I'v heard, yet I don't like having a big cpu cooler in my windowed case ~.~

Closed loop cooler is a glorified heatsink and fan cooler, the Hyper 212 is not the problem as it can keep a overclocked 6800K to under 50C. Haswell is just hot period.

lol haswell "just [being] hot" is not the reason for the temps that cagethemoose is having.. at least not with a working 212. According to him the 212 isn't operating normally (this is evident if you read previous thread answers) and so it is in fact "the problem" .

Should have mentioned, With Hyper 212, as with most HSF that have valleys on the base - YOU must properly apply the Thermal paste - IT IS DIFF than a Flat surfaced HSF.
Flat surface - Peas sized amount (I spread with latex gloved finge.
Heat pipe surface - FILL the valleys, use old credit card so that only the valleys have Paste then use the diagonal line.

Myself I have the Zalman CPS9900 Max and it does a great job. i5-2500k @ 4.2 is just 60C (Summer time) and upto 4.8 does not break 70C.
As for H20, They can be very effect with the higher OCs. Myself I prefer the air cooled - BUT to each his own!!

sounds like things are getting better Happy gaming and don't forget to pick the best answer ; )

When you picked the performance setting you picked an overclocking setting.
Run cpu-z and your stress test. I bet you will see a high multiplier, and a vcore of 1.3v or more.

Thats a easy situation to diagnose, either the fan spins at full tilt or its defective especially plugged into the CPU/Fan header, the trouble shoot is to take another 120mm and connect it if it spins then its the busted sickleflow they send with it. But the HS itself should absorb a lot of the heat and displace it. Closed loop is more severe, failure on the pump will spike temps to thermal shutdown in almost no time at all.

99 is high but not worry some. Haswell is obnoxiously hot. Mine bit 105 and would have gone higher had I not set that as my tj. That was on water.

You are fine to game or do whatever else u want. There is NOTHING apart from stress tests that will hold your cpu at 100% let alone 100% on all 4 cores. Even if there was it wouldn't be cycling small ftts for that exact reason.

While I would suggest reseating your hsf and re applying your TIM - nothing short of a delid will get your temps much lower than 80s with IBT. If you run prime it generates a bit less heat than intel burn test but your still gonna see much higher temps than you would earlier i7s.

Sad but true.

They're heat pigs as it is and our good friend Intel decided to use el cheapo TIM between the IHS and the die instead of solder to add to the problem. At 4.6 with a naked chip on water I'm hitting 68 as we speak with a pretty low vcore.

If you delid properly you can drop 20 off your temps instantly.

I highly doubt your heatsink is defective. Start at square one, and follow these steps below. Not installing the heatsink properly, or applying to much paste will cause problems immediately. On a side note, do not delid your cpu. You mentioned that this is your first build. Get some confidence first. Run your cpu at stock speeds for awhile, and find some forums concerning your motherboard. Start learning some of the basic settings in the bios, and make sure your ram timings are correct. This is were you need to start before set anything to performance, and start running prime tests. Just take it slow. You'll be surprised how quickly you'll learn, when looking in the right places.


I have installed the Hyper 212 plus and Evo several times. The directions are incomplete imo. This is my method how to properly install the Evo.

* The 212 Plus is a little different. The gaps on the heatsink should be filled in before applying paste. Not true with the Evo. The Evo has a smoother surface area vs the 212. Other than that, the same steps apply.

Here are my tips.

1.Use a green pea size drop right in the middle of the cpu. Actually, the size if a Nestles chocolate chip. Just a wee smaller than a pea. How do you know if you used the correct amount ? When paste is not leaking out the sides when you have it fully tightened down.That is very important.

2.I'm sure you noticed the the push pins on the bracket. There adjustable for different lengths. Make sure all 4 pins are adjusted for Intel.

3.VERY important. This is where people make mistakes. Never put the cooler on the cpu first, and then try to adjust the bracket, after the fact. Your cooler will slip and slide before you get it clamped down.

4.Put the bracket on the cooler, just like you would if it was fully assembled sitting on your board. With no paste on the cpu, do some dry runs. Don't touch the cpu, just go through the motions. This will help you adjust the bracket very close to the holes when it counts.

5.Put on the paste, and drop the cooler on the cpu evenly. Your bracket should already be lined up to your 4 mounting holes. Make sure your using a longer Phillips head screwdriver, as this helps. Notice the groove on the sides of the cooler. A longer phillips helps. Tighten each opposite corner a few turns, then the other opposite corners a few turns. Repeat until is is fully secure. After it feels tight. Give it an extra 1/4 turn.

6.The cooler can mount with fans facing front to back or top to bottom.Just in-case you didn't know.

Hope that helps. Good luck.
