i5 2500K thermal paste or heatsink? Cooling question!

post #1 of 74
Thread Starter 
I just bought a brand new computer and I have a i5 2500K and a hyper 212+

First off I did a standard 4.6 GHz auto overclock in the EFI bios with my motherboard. I ran Prime95 for 40 mins and the temps on the hottest core got to 73*C. I stopped the test.

I just ran Prime95 again today on the exact same settings and in about 1-2 mins the temps shot up to 73*C again and I stopped the test.

I also tried to put it at 4.8 GHz with some manual settings changed and the voltage was set to 1.47V and it got to 73*C in a few seconds. Really hot VERY fast.

Now my question is what type of issue is this? My brother says this is the thermal paste and I feel its these auto settings are making it extremely hot because they aren't optimized for overclocking. I really don't think its the Hyper 212+ because many many many people use it and seems to get high overclocks. I also have the additional fan on the other side to make it push/pull. I feel its either the thermal paste or that the setting are all screwy in the bios which is making it hot. I'm really new to overclocking to I've been using the auto overclocking settings because it does it automatically.

PLEASE ANY ADVICE WOULD HELP A LOT!

PS. I applied the thermal paste in a straight line across the CPU. I'm going to take off the heatsink cooler and check the paste and probably reapply it.

Please go here and fill in your system spec so we know what components you're running.

secondly lets try and see what kind of temps you get under stock. Auto or software overclocking is garbage compared to what you can do in the BIOS, however before we get to that lets try and see what your temps are.

Regarding the paste a line maybe too much, usually flat based heatsinks only require a small uncoocked grain of rice amount on the cpu and the pressure of the cooler does the rest. Coolers such as the 212+ are not really flat based, forgotton what they were called, HDT heatsinks I think and the way to apply the paste is by applying it on the actual heatsink between the cooper pipes that are visible like so:









By the way make sure you download the latest realtemp to read the temps, you can grab it from here: http://majorgeeks.com/Real_Temp_d6098.html


Hope that helps answer your questions.

EDIT:

clear the cmos or set the default settings in the BIOS set the RAM to XMP and report back with temps under load, don't use IBT or LinX for that, prime is a littel more realistic, on that note use prime blend to do all your stress testing, however we'll get to the BIOS overclocking a little bit later on.

Regarding 'high' temps have a little read at this (my opinion):



****Max Safe Voltage and Temps****


Before I go into this, I just want to say that this is my OWN opinion and take it as you will.

No one is absolutely certain of what the safe vcore is for the sandybridge chips. What I can tell you is that many say the max safe vcore for these chips are 1.3 region, however, intel states that the max 'VID' is 1.52 and many say that around 1.4 if your on air and 1.45 should be the max if your running water cooling. Personally I will not go above 1.5v for 24/7 with these chip but that is totally upto you. The main thing to understand is that 'YOU' have to come up with the conclusion of what the max is. That way no one is blamed if the chip degrades (none reported so far, even with so called 'high 1.4+ vcore')

Those that have killed or degraded their cpu's have done so through either by their own fault, running sucide runs with crazy voltages and by not having substantial cooling for their overclocks and voltage or for reasons like their mobo or PSU causing shorting and also BIOS bugs.

Please remember that not all chips are the same, some can do high overclocks with low voltage some cannot.

Regarding temps, CPU throttles at 95c, some say keeping it below 85c is good, some say keeping it below 80 is better, other's say below 75c is really good and there are quite a few that say 70c should be the max. Which ever one your comfortable with and if you have substantial cooling, YOU DECIDE YOUR MAX, just remember it throttles at 95c. If for example you hit 85c in stress testing then in everday usage it shouldn't be higher than 75c which I think is fine, I personally like to keep mine below 70/75c during general everyday usage

Thank you so much for posting this info. So I updated my information in my sig with my specs.

So I just realized I think that if the comp crashes or doesnt boot I can look at the little led display on the mobo for what is the issue? I didn't know that.

So basically what you are saying is u want me to RESET everything back to stock, like 3.3 GHz, stock everything, reset bios and all, and tell you temps on Prime95?

I'm a little confused what you want me to do.

I also had an out dated version of real temp. Maybe that did something too.

I wouldn't recommend the Hyper 212+ for speeds above 4.5GHz. I would go with a NH-D14.

73 degrees is really good for 1.47v. At 1.32v I get around 70 degrees load in Prime95.

Non ononononon lol. It instantly shoots to 73*C i have to turn it off or it will completely melt my CPU. I bet it would go to 100*C+ if I left Prime95 open for an hour.

I dunno whats wrong. I see people use Hyper 212+ all the time in CPU's. I dunno I guess they arent overclocking that high.

But like still even at 4.6 GHz My temps are going extremely fast to like 75*C and I turn it off because I'm sure it will overheat really badly if I keep it on.

Ok so I just wanted to push it a little to see how quickly and if this would level out in the 70's at all, but basically 5 mins into Prime 95 I hit 77*C and it was still going up quickly. Basically every 30 secs it would gain 1 or 2 degrees. It would prolly cap out around 85+... I'm getting worried now. I don't know why my temps are so high.

Stress testing always shoots the temps real high, real fast. It gets hot and then takes about an hour to get its hottest.

The reason he asked you to prime at stock settings is so you can get a baseline measure of temps to compare. If you are still getting 73c with stock, it might hint at other factors like improper installation, improper use of thermal paste, case airflow, and so on.

The auto oc settings are quite optimistic with voltages. Their goal is to maximize success and stability, the trade off is that they often use much more voltage than actually necessary. For this reason, many overclockers will insist on doing the settings manually in bios.

There are a plethora of guides around the web. Read and understand them, then attempt the oc. Always come back and ask if you are stuck!

That's what prime95 does. Intel burn test will be even hotter. I don't think your results are abnormal at all. You need to learn more about computers, overclocking, and stress testing. I bet you arent even stable at that speed.

Here are my temps completely stock. Reset all settings and CMOS and everything. 5 Mins on P95 for a quick check of temps
