780i/TRUE Cooling Dilemma

post #1 of 12
Thread Starter 
I feel like a noob. I was smacked in the face with the reality that is Coretemp and realized my "sweet" temps that I was reading from Speedfan were just a lie. I was under the impression that my dual fanned TRUE was giving me 25c @ idle/37c @ load on my E8400, but after checking out coretemp (*** took me so long to find this?) I'm really sitting at 45/47 @ idle and up to 50/60 @ load. Reseat, reapply shin etsu time.

So I popped off the TRUE and reapplied the shin etsu and realized that even after tightening the bolts as much as possible, I can move my TRUE if I apply modest pressure - this can't be good.

So, one of my questions is this: is this a problem with the base of TRUE not being as flat as it should or a problem with my shin etsu application (it was a thin line across the base of the cpu, vertical with the mobo)? I'm thinking I should bust my lapping cherry and find a kit to do it. Anyone know where I can find a decent kit online that would ship to Canada? This one from FrozenCPU was the only one I could find. I know there's a TRUE lapping thread somewhere on here...

Anyone have any tips for shin etsu application?

Also, my chipset temps are terrible () - 52c on the MCP @ idle, seen it go as high as 60 - so I was thinking about picking up a few of Thermalright's chipset and mosfet coolers:
HR-05/IFX for the Northbridge
HR-05/SLI for the Southbridge
HR-09/U Type 3 for the Mosfet - this one is questionable, while it looks like it should fit, with two fans on my TRUE, I'm not sure which Type to choose for it.
I shouldn't have much trouble mounting these on my 780i, should I? Keep in mind while I don't have a dual card setup now, I'm hoping to have one sometime in the next few months.

Any help or suggestions are appreciated.

ive got the TRUE with 780i as well.

Those temps actually arent bad is youve got moderate intake and an ambient around 22C.

->on my Q6600, unlapped, with unlapped true (I checked the contact by putting the true upside-down an the CPU on it: perfect fit, no light whatsoever)

I get 3-4 lower, my ambient is 21C, in a Cosmos Case with front intake mod. Note that when i check idle temps, i make sure CPU is running at 0% for at least 5 mins.

As for the changing your mobo cooling, im doing the same. Im getting an HR-05 IFX for NB, (if it fits) an HR-05 IFX SLI for SB, as for mosfets, I dont think the HR-09 will fit near the I/O panel.

Tell me if you find any good mosfet cooler. We're 3 in the same boat.

With the CM690, I've got two 120mm front intakes (one at the same level as the cpu), one 120mm on the bottom @ 110cfm, and one 120mm on the side panel. Given the idle temps I've seen in the TRUE info thread, I should be getting at least 10 degrees lower.

Can you twist your TRUE, slightly, while it's bolted on?

same setup here, your completely fine man, my NB is idle at 60, but does not move under load.. i use AM fan for it tho

And your CPU prob has faulty temp sensor... mine does !

It is normal for a slight rotation movement and shifting of the heatsink even with all four screws as tight as they'll go. If you want to improve the mounting pressure, stick a washer (you can get them from any hardware store) between the heatsink and the scissor-style hold down plate.

Yes lol thats completely normal.

How i used this to my advantage:

1- Run Prime95 on 100% for 5 mins or untill temps stablilize

2-twist the 120 a bit, and notice temp changes.

3-Keep twisting it in different ways until you find an angle that gives the best temps.

This made me lose 5C off idle. and another guy i told it to lost 10c.

Adrienspawn, is it safe to move the TRUE while the computer is on? Or did you shutdown in between each turn.

Unless your unscrewing the base, turning the TRUE is fine while on AFAIK

Good idea. I'll give it a shot and let you know how it goes.
