Ok I a problem, i think, and some questions

1. Box says fan speed is 1450-2000rpm, My ASROCK AXTU Tuning Utility shows my fan speed sitting around 1390rpm? Whats with that, where is my 2000 rpm to keep my rig cool? I read this whole thread and you guys talked about rpms a little but nothin anwsered my question, but one guy did say if your speed is at 1390-1400 its at 100%. Can someone Explain?

2. I idle around 34-35C, is that good? But my full load got up to 70C using prime95! Where is my 50C like everyone else? =( I got a Antec 900 Two V3, all fans maxed, and a push pull on the 620. My office is isnt really that hot so there is something going on here.

plz help! thanks!


ps, i did put artic silver all over the cpu when building my comp, i read on this thread that someone said dont put tooooo much, but how much is too much? I just covered the surface of my cpu, not just a little drop.


LOL sorry for laughing but yeah you already put too much thermal paste. AS5 and some other good brands need the smallest amount possible where it will cover the cores.

Too much is just as bad as too little. Too much will almost act as a barrier to thermal conduction. Too little and the thermal conduction wont even take place. Then you have to worry about air pockets depending on your method of use.

The way I always do it is a very tiny bead or bb in the middle of cpu. The PSI during clamp down will spread the TIM. Then the cycling of normal use of the computer will break in the TIM and allow for better temperatures as it spreads evenly.

For IC Diamond i needed a lot. A giant pea worth after some trial and error.

For you I would suggest reseating a few times.

Take off the pump.
Clean both Pump AND CPU! (lol some noobs dont clean after checking and just tighten it back down with massive air pockets)

Put a tiny BB in center of CPU. ( With AS5 or MX-2 you can spread a very very very thin layer on the pump's contact plate itself, you just want a light haze on the pumps plate. Then just a BB on the CPU)

Put on pump, twist while applying force. ( Twist a small amount, I do about 1/4" each way once)
Screw down with appropriate PSI.

NOW
UNDO EVERYTHING
Check your spread and if it looks good:
Clean pump and cpu and apply the same amount of paste and do everything as before, twist and clamp the sucker.

Then check TEMPS. If its too high reapply and find the right amount for your set up.

I check the spread this way and see which method works best for my set up by checking for air pockets and correct form. Also when you check your spread you want to be able to see the metal under it, eg IHS (intels cpu cover thats welded on the cores)

Like I said, not too much or too little. GL:thumb:

The only thing I guess I really have a question about is the fan speed. I only have 2 options in my bios, "full on" and "automatic". I kept it on default full on. With that being done, why is it not going over 1390 rpm?

Thats how mine runs. Its full speed and m in the 1300s for rpm. Lots of people I've seen reported the same. Should be fine as long as pump doesnt die.

If CPU shuts down then temps got too high because either fans stopped while doing something intensive, pump stopped or you kicked the power plug. Ive kicked the plug a few times and everything in my room turned off. Thought we were in another black out. I got everything in my room running off a belkin power strip because only 1 outlet has a ground frown.gif

Thanks for the tips guys! Yeah I guess since its running at 1390rpm ill just leave it alone? As for the thermal paste, ill take it apart and reapply!

thanks!

NP man. GL!

Also I just wanted to point out, people are reporting a mix of AVX and non AVX stress testing temps. Watch out for that so you know what you get into because AVX raises temps by a good mount. I gained minimum 5 degrees with AVX. Also requires higher vcore.

Without AVX I'm also hitting in the low 60s. I'm only at 4.4ghz tho frown.gif

hhmm i dunno what AVX stands for, but im in the upper 60's when i run prime95, here is my system, soemthin could be wrong i dunno

intel 2600k OC to 4.0 no voltage change
antec 620!
8G DDR3 1600 8-8-8-24
ASRock extreme4 mobo
evga gtx570
antec 900 two v3
WD caviar black 500g (ssd soon to come)
antec 750W PS



I just dont see why im in the 70C area when stress testing, thought the antec 620 would bring me into the 50's

Dont forget i7 has hyper threading. That alone is going to increase your temps.

I only used dual and quads so cant help you from experience on that. But from what I've been reading for an i7 it sounds about right.

AVX is Sandy Bridge instruction set. If you have SP1 installed download LinX with AVX and run that. Avx is on the SP1 update for Windows 7.

I do have an i7 laptop that hits 80+ degrees tho lol.

The 1390rpm is the pump speed and should be always full on. You can plug the included fan to a 3-pin board connector to change the rpm/voltage.

No one knows what to do about the clicking issue? I have the pump and fans plugged into the CPU_fan port, as the manual suggests. I checked in the BIOS (using a P67A-G45) and didn't see anything relating to fan control or something like that. Should I just keep the thing plugged into the PSU at all times? (Using non stock fans so don't think noise is going to be an issue)

I'll give it a shot later but what if it continues? Do antec usually send a new unit out before you send your one back so you don't have to be without a cooler?

Also, how about the paste question I asked on the last post? Thanks.
post #339 of 6068
So I have the 620 plugged in to the CPU fan header and everything, but just in the UEFI menu it is at 96 F? Also I need to install the Antec software to turn on and change the LED colour correct?

Whats going on!?

The 620 doesn't have any software and no LED. Check if the pump is running you should feel some vibrations, the temperature seems to be normal to me.
