raffreddamento ram
in questo campo nel 90% dei casi applicare dei dissipatori aggiuntivi porta a pochi risultati o comunque porta a risultati ottenibili tranquillamente anche con una sola 120mm downvoltata a 5v.
comunque prendiamone in considerazione qualcuno ed elenchiamolo secondo la sua potenza dissipante:
ddr2/ddr3
1-Thermalright HR-07
2-OCZ XTC Memory Airflow Cooler
3-Thermaltake Cyclo Ram-Cooler
4-Zalman ZM-RHS1
ed ecco i prodotti:
thermalright
thermalright hr-07/duo
specifiche tecniche:
Dimension:L150 x W27 x H86 mm (Heatsink Only)
Weight:150g (Heatsink Only)
Recommended Fan:70mm ,80mm ,92mm Fan
Compatibility
DDR1 DDR2 Single Sided Memory Module&Duble Sided Memory Module

Important Note: In order to install HR-07, you will have to remove the heat spreader on your memory module. However, Thermalright is not responsible for any problems or damages that may occur during the removal of memory heat spreader. Users will be at their own risk. If you are not sure or do not know how to remove/uninstall your heat spreader, please contact your memory manufacturer for instructions.

Per quanto concerne i mosfet per ora l'unico dissipatore degno di nota che mi sento di consigliarvi è questo:
thermalright hr-09s
specifiche tecniche:
HR-09U
- Dimension : L84 x W17 x H48
- Weigh t: 90g
HR-09S
- Dimension : L84 x W32.3 x H48
- Weight : 90g (heatsink only)

Rivolgiamo ora la nostra attenzione verso l'amata gpu che sempre più spesso viene overclockata ai suoi limiti ma senza un adeguato sistema di raffreddamento causando poi come ben sappiamo problemi di instabilità ed artefatti......
Tra le varie case che producono dissipatori per vga troviamo la zalman,thermalright,artic cooling,revoltec,thermaltake ed aerocool.
l’argomento verrà preso per i dissipatori dalla serie 78**/79** per le vga nvidia e dalla serie 18**/19** per le vga ati per ovvi motivi logistici e amministrativi della guida nonché per far si che la cosa non diventi dispersiva ma che rimanga aggiornata ed efficacie nel tempo.
andiamo ora al nocciolo della questione e incominciamo con la ‘’presentazione’’ dei dissipatori per vga della serie 7800/7900 di invidia.
come di consueto i dissipatori sono presentati in ordine performante sia in termini di potenza dissipante che di silenziosità cercando di fare una media tra i 2 fattori.

prima di effettuare l'acquisto controllate sempre la compatibilità poichè un dissipatore può essere compatibile con la serie 7800 ma nn esserlo con la 7900
