95c+ Temps in Prime 95

post #1 of 26
Thread Starter 
Just built a computer for the first time.
Quick specs: Haf X case(6 fans) i5 2500k, P8Z68-v Pro motherboard, Corsair A70. CPU usually idles around 35c, ~60c under gaming load.

First time I seated the cooler I used a small pea sized amount, and made sure to first prep the gaps between the copper pipes and base plate, then I tightened each screw evenly till seated.

When I run Prime 95, within a couple seconds it goes from 35c~ to 90c+ easily. When I turn it off, within a couple seconds it goes back down towards idling temps. I was confused and thought I maybe seated the cooler wrong, so I took it off and the paste was cover about 90%~ of the processor. Now that it's reseated, it's the same if not worse than before.

The cooler fans are pointing towards the rear exhaust fan.

Can anyone tell me what might be wrong? I really want to get these temps under control so I can have a stable overclock goal of 5ghz.

What kind of voltage are you using?

What cpu monitoring program are you using? RealTemp and CoreTemp are good programs. I've heard that it's best to put a line of thermal paste on each heatpipe with direct touch heatsinks.

Using the Asus Turbo-V, I just set the volt to 1.420 but I think it auto-adjusts to what it needs. Under load, it might spike to 1.56 and give me a warning, even though I can't find a way to limit it.

I'm using Asus' AI Suite that came with the mobo. I think I will try that method. Could it be the thermal paste that came with the A70 needs a curing time? Stupid me, I remembered about filling in the gaps between the base plate+copper, but not the line on the copper pipes.

Definitely do not use AI Suite. I used to use it until I realized how off the temperatures are shown in that program. It shows 10 degrees lower than 3 other programs: RealTemp, CoreTemp, and a desktop widget that I use (they all show the same temp).
I'd use a more reliable program. I don't know for how long I thought my cpu was at 70 degrees while I was overclocking when it really was at 80 or maybe close to 90...which is way higher than I would want my chip to be at.

I don't see any reason he can't since the program is made by his motherboard's company and all it does is change the settings in the BIOS, which he can do himself but w/e it's the same thing. He still has to restart the computer anyway.

What's wrong with using it? Should I just uninstall AI suite all together?

One would think the software for its own mobo would be accurate. What a shame. I will go download those programs now.

It's been said before but I'll say it again: Do not use AI Suit to OC your rig. Read a few Sandy Bridge OCing guides and start low (4.3Ghz) or so and work your way up. Everyone wants to hit 5Ghz but for a lot of people it's not practical for daily use unless you have a good chip and good cooling. There is nothing wrong with 4.5-4.9Ghz, don't risk killing your CPU just to get to 5.

You don't have to uninstall it, just don't use it to overclock your PC. Manually change it yourself in the bios.

The only reason I use AI suite is to control the cpu fan speed.
I just use q-fan. btw the q-fan mode automatically adjusts the cpu fan speed like normal. With duty cycle you choose the fan speed. I'm just telling you this since for some reason I didn't figure that out for awhile lmao

Ok, I uninstalled AI Suite, set everything in bios to default, restarted and started off at 46x and turned off this thing called internal PLL overvolt? Im just guessing that was the thing that was letting my cpu spike 1.5+ v.

Quick stats during prime 95 100% load test:
4.6ghz(100blck)
1.440v
Temps are 80c~in both real and coretemp programs. Does that seem a bit too high?
