i7 920 Temps

dylskee · 10-23-2009, 09:45 PM

I've been having a bit of a problem with temps on my 920 and I was looking for some suggestions. My 920 is clocking pretty well so far but my temps seem to be pretty high and I'm getting worried. So far I'm running @4100MHz with 1.2875V and my Idle temps are 48-46-48-44 and Prime95 load 93-91-91-88. I tried reseating my waterblock 4 times and always end up with the same results. My GPU loop seems to be holding up pretty well, I've got two BFG GTX 285s and they Idle around 32~34°C and load in the 50s. I'm not sure whats going on with the CPU, could I just have a damn hot 920?

Even at stock my Idle temps are 38-33-36-33 and load temps are 63-59-60-57. This is with HT on, does anyone else see really hot temps like this with the 920?

here's my Bios settings.

That's waaaayy too hot for the cooling you have unless your room is like 40c...lol. How does the TIM spread look when you pull the water block off? Have you taken the block apart recently to check for sludge?

These Q's, plus a full loop breakdown (including fans used and tim) and we should be able to help you better. That seems way too hot.

dylskee · 10-23-2009, 10:33 PM

The TIM looks good when I take the block off, I've done this a few times now. I'm not new to water cooling so I know what to look for but this is killing me! This loop is for the CPU and chipset, I'm running an XSPC dual bay res and pump combo with MCP350s. The loop has a MCR320 with Gentle Typhoon 1850s with a Swiftech GTZ.

Using AS5 and have reapplied several times to no avail!
And I'm running a MCR220 for my dual GTX 285s and my temps are 32°~34° and load no more than 50°C.

fallwind · 10-24-2009, 01:59 AM

You say you're not new so I'll assume the rad fins are clean and there's nothing blocking airflow like fan filters, etc. Is the water in the res nice and turbulent indicating good flow? Maybe take a thermometer and measure the coolant temp. Just stick it in the fill hole on the res. Anything more than 10c over ambient at full load indicates poor rad performance. If the flow is good and the coolant is the right temp, then that leaves the water block or TIM as the culprit. I guess there's always the possibility of a defective solder between the core and IHS but your temps are nice and even so I doubt it.

faster3200 · 10-24-2009, 08:58 AM

Well, AS5 does have a cure time, although I doubt it will be more than a few C. Kind of an odd problem you have there.

dan7777 · 10-24-2009, 09:06 AM

im having the same problems mate running my i7 megahelems cooler idles 40c load 80-85 4.2 HT on turn HT off temps will drop 10c+

This is a new build so everything is clean, no dust or filters. I don't even have the side covers of the case on yet. I couldn't find a thermometer but I stuck my finger in the res and the coolant feels pretty cool and the pump is working well so maybe it's just a hot chip.

Yeah that wouldn't account for my really high temps but the first application of AS5 I did burn in for a day.

I'm just not seeing many people complaining of the high temps that I'm experiencing so I'm a little confused about what's going on here. My load temps drop quite a bit when I turn off HT also.

Load temps dropping when you turn off HT is normal for i7's. No problem here.

However, your reported idle & load temps are definitely on the high side of the norms for your configuration.

Yeah, definitely! I don't like the delta from Idle to load, I've never had a delta of 45C on water before. When do these chips start to throttle anyway? I have seen my temps as high as 94C when running prime for an hour. I'm not going to load my cpu until I figure this out. All I can do now is try a different waterblock or CPU, I just ordered another 920 lastnight and i'm thinking of trying out a Heatkiller block.

I do not remember the exact number. I expect that you are knocking on the door. However, read this thread ( http://www.xtremesystems.org/forums/...ighlight=turbo ) for a detailed understanding of i7 thermal throttling. UncleWebb is the in-house expert on this topic. His tool will confirm if throttling is an issue in your configuration.

dylskee · 10-30-2009, 12:07 PM

Well I got a hold of another 920 today and it's a completely different batch number (FPO/Batch # 3919B011) and the temps are the same as my first chip actually a littler higher under load.

Idle temps @ stock: 35-32-37-30
Load temps @ stock: 68-67-67-65

It's got to be something with my water loop, the possibility of getting two hot chips are not very good. I'm running a dedicated loop on the cpu with a GTZ and chipset with a triple MCR QP with typhoons 1850s, MCP350 pump mounted on a XSPC dual split res. Order is Res/pump>CPU>Chipset>Rad.

Here's a picture of the loop, keep in mind I'm nowhere close to finished so no wire management suggestions.

Still have a lot of sleeving to do before I finish this up. Just trying to get the high temps figured out, any help or suggestions would be appreciated.

woffen · 10-30-2009, 01:48 PM

Maybe having the rad before the CPU could help knock off a few degrees

Another thought, you have the GTZ fitted the right way, and no secret huge pockets of air in there..

I'm not looking for a few degrees, my temps are about 20C higher than most with similar setups. As far as fitting the GTZ properly not sure what you mean? I have the inlet as the lower left hand as the instructions indicate.

Conumdrum · 10-30-2009, 05:08 PM

The GTZ inlet has a small dot for the in side of the block.

Have you opened the CPU block to check for stuff? Or the NB/SB block? Never know?

+1
Even new builds can have manufacturing defects or debris blocking critical locations within the block.

Yeah, that's my inlet. I haven't opened the blocks yet I was saving that as last resort but it's becoming more of a reality now. I was trying to avoid breaking down the whole setup but that might be my project for tomorrow.

woffen · 10-31-2009, 12:41 AM

Well, every degree is a start to getting where you want imo.

EDIT:

This is what I meant with proper installation of the GTZ:

To me it looks like you have the block installed "wrong", and not according to the picture on Swiftech's homepage.

Just woke up and my eyes are merely starting to open so I might just be looking at it the wrong way

No, I think you're right, woffen. I think he's got his block installed 90 degrees off of what it should be if the motherboard is a Classified 760. His locking lever is, looking at his posted pic above, along the right side next to the RAM slots, so the block should be turned 90 degrees counterclockwise to match Swiftech's mounting pic.

Might help with the temps.....certainly isn't helping his situation out at all, anyway.

Oh believe me I realize every degree counts, I didn't mean to sound condescending I was just looking for the underline problem first then i can tweak my final results.

You're absolutely right about the orientation of the block! I must have rotated the block when I got everything put in my case and set for water cooling. Right now at stock settings with prime load my temps have dropped 10°C, the idle are about the same. Thanks for the help woffen!

rmorse27 · 10-31-2009, 07:52 AM

while your fixing block put the rad just before cpu.

Good I was right for once

Yea, I would recommend that as well and maybe get a few more degrees off of still

dylskee · 10-31-2009, 03:27 PM

Well, back to square one again. My load temps dropped 10° but after about an hour of prime95 they creep back up to 90-89-87-84. Think I'm going to break apart the loop tomorrow and check the blocks for any particles floating around. Could it be the MCP-350 pump not having enough flow? Another thought is a new cpu block, maybe a HK or the XT.

creidiki · 10-31-2009, 03:39 PM

If it was the pump not coping (ie broken, because a working DDC has plenty of head for that) then your whole loop would probably be in trouble - its just your CPU.

So its probably just your CPU block. Take it apart and see what's up.

Hmm, you got the basic 350, two rads, two GPU blocks and a CPU block all in one loop? And you say it took a long time for your temps to get high again?

Your pump could be a bit of the issue, can you mod it to a 355? Your running good fans at what speeds? And what is the case setup for both of those rads? Wondering about case airflow. Forgive me if you have told us that info, I might of missed it.

Is there a chance you have an old GPU air cooled? If your gonna tear the loop down try watercooling just the CPU. I know it's a lot of work, but you just might have too much heat at 4.2 and both GPUs for your total rad size.

Just tossing ideas out there.
